NKSP: Allow more wider support of standard measuring units & 'final'ness.

* Raised compiler requirement to be C++14 compliant (due to severe
  restrictions regarding C-style aggregate initializer lists in C++11
  which are now massively used throughout the code base).

* NKSP VM API: Allow units and 'final'ness to be returned as result from
  built-in functions (added methods VMFunction::returnUnitType() and
  VMFunction::returnsFinal() for that purpose which must be implemented by
  built-in function implementations).

* NKSP language: Allow metric unit prefixes of numeric scalar and array
  variables to be changed freely at runtime (unlike unit types like Hz etc.
  which are still sticky parse-time features of variables which cannot be
  changed at runtime for the intentional sake of determinism).

* NKSP language: 'final' values are prohibited for array variables for now
  (attempt causes a parsers error).

* NKSP language: expressions with unit types (e.g. Hz) are prohibited for
  conditions of runtime control structures like if(), while(), select()
  (attempt causes a parser error).

* NKSP VM API: Allow built-in functions to perform their own, individual
  parse time checks of arguments going to be passed to the function at
  runtime (added method VMFunction::checkArgs() for that purpose).

* NKSP language: raise parser warning if only one operand of binary
  operators (like logical 'or' comparison) contain a 'final' value (because
  it would always yield in a 'final' result in such cases).

* NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
  different metric unit prefixes, which will behave as expected (e.g.
  result of expression '1000us < 2ms' is true).

* NKSP language: Allow adding values with different metric unit prefixes
  (e.g. result of expression '100Hz + 5kHz' is '5100Hz').

* NKSP language: Allow subtracting values with different metric unit
  prefixes (e.g. result of expression '1ms - 20us' is '980us').

* NKSP language: Allow multiplying with any metric unit prefixes
  (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
  with unit types on both sides (e.g. '2s * 2s') is still prohibited since
  we don't have any considerable practical use for a term like '4s^2'
  (hence any attempt multiplying two unit types still causes parser error).

* NKSP language: Allow dividing by any metric unit prefixes and allow
  division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
  yields in unit free result '8'). So this is now a way to cast units away
  e.g. for passing the result to other expressions, certain function calls
  or variables which are not accepting any units (or that specific unit).

* NKSP language: integer arrays and real number arrays can now be converted
  to strings (e.g. for dumping their content with message() calls for
  script debugging purposes).

* NKSP language: expressions and variables with units are now correctly
  casted to strings (e.g. with message() calls).

* NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
  unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
  floating point tolerances into account.

* NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
  VMScalarNumberExpr::evalCastReal().

* NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
  'VMIntArrayExpr' and 'VMRealArrayExpr'.

* NKSP VM API: replaced all unitPrefix() (parse time) methods by
  unitFactor() (runtime) methods.

* Built-in function "exit()" supports now returning units and 'final'ness
  exclusively for test cases.

* The following built-in functions support now units as well: "abs()",
  "random()", "inc()", "dec()", "in_range()", "min()", "max()",
  "real_to_int()", "int()", "int_to_real()" and "real()".

* Built-in functions "array_equal()", "search()" and "sort()" support now
  real number arrays (correctly) as well.

* Added individual parse time checks of arguments to be passed to built-in
  functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
  "array_equal()" and "search()" specific for their individual purposes.

* Test cases: Added massive amount of NKSP test cases for standard
  measuring units and 'final' operator usage cases.

* Test cases: Added NKSP test cases for (floating point tolerance aware)
  real number equalness / unequalness comparison.

* Bumped version (2.1.1.svn8).

Diff to previous 3564 , to selected 2945
NKSP: Introducing variable return type for built-in functions.

* Changed method signature VMFunction::returnType() ->
  VMFunction::returnType(VMFnArgs* args) to allow built-in
  functions to proclaim a different result value type depending
  on the arguments to be passed to the function.

* Built-in script function abs() optionally accepts and returns
  real number.

* Built-in script functions min() and max() optionally accept
  real number arguments and return real number as result in that
  case.

* Added real number test cases for the built-in abs(), min() and
  max() functions.

* Bumped version (2.1.1.svn7).

NKSP: Bug fixes regarding new measurement units feature:

* Fix: Engine internal Fade of script synthesis parameters volume, pitch
  and pan were not rendered at all.

* Fix: Backward compatibility of built-in function arguments without a
  metric unit prefix was broken (resulted in incorrect value
  transformation).

* Fix: built-in script function change_play_pos() resolved wrong arguments.

* Bumped version (2.1.1.svn5).

File length: 25939 byte(s)
Diff to previous 3557 , to selected 2945
NKSP: Added standard units support for numbers and final "!" operator:

* NKSP strictness: Variable names, function names and preprocessor condition
  names must start with a regular character (a-z or A-Z); starting them with
  a digit or underscore is no longer allowed.

* NKSP parser fix: equal comparison operator "=" and not equal comparison
  operator "#" must only accept integer operands.

* NKSP language: Implemented support for standard units like Hertz, seconds,
  Bel including support for metric unit prefixes; so one can now e.g.
  conveniently use numbers in scripts like "5us" meaning "5 microseconds",
  or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
  "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).

* NKSP language: Introduced "final" operator "!" which is specifically
  intended for synthesis parameter values to denote that the synthesis
  parameter value is intended to be the "final" value for that synthesis
  parameter that should explicitly be used by the engine and thus causing
  the sampler engine to ignore all other modulation sources for the same
  synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
  variable or formula with this new "!" operator the expression is marked as
  being "final".

* Bumped version (2.1.1.svn4).

  (e.g. -std=C++11).
