Added new LFO implementations:

* Added int math square LFO implementation.

* Added int math saw LFO implementation.

* Added numeric complex nr sine LFO implementation.

* Added public API C++ class "LFO", which is a cluster class
  encapsulating all the sampler's LFO implementations to be used by
  3rd party applications (e.g. by Gigedit).

* Marked class LFOTriangleDiHarmonic as deprecated
  (will be removed in future).

* Added LFOAll.h which includes all LFO implementation's header files.

* Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
  algorithm (since result of 2nd run was not accumulated).

* Added benchmark for saw wave (benchmarks/saw.cpp).

* Added benchmark for sine wave (benchmarks/sine.cpp).

* Added benchmark for square wave (benchmarks/square.cpp).

* Increased amount of benchmarks runs by factor 6 to achieve benchmark
  times which are large enough on modern systems.

* Cleanup of LFO APIs.

* Bumped version (2.1.1.svn18).

19     // implementation (either because the configure script's benchmarks picked the
20     // most fastest/efficient implementation for this machine, or because the it was
