* ScriptVM (WIP): Built-in script function "play_note()" now returns the
  event ID of the triggered note.
* ScriptVM (WIP): Implemented built-in script int variable $EVENT_ID.
* ScriptVM (WIP): Implemented built-in script function "ignore_event()".
* ScriptVM (WIP): Implemented built-in script function
  "ignore_controller()" (accepts one and no argument).
* Bumped version (1.0.0.svn44).

22 * Extends the core ScriptVM implementation with MIDI specific built-in
23 * script functions and MIDI specific built-in script variables required
24 * for MIDI processing by instrument script for all sampler engine
25 * implementations (sampler formats) of this sampler.
26 *
27 * Note that this class is currently re-entrant safe, but @b not thread
28 * safe! See also comments of base class ScriptVM regarding this issue.
