Squashed development into 0.5.0
Fixed some problems from merging
 - Changing interpolation type to bezier now preserves linear & cos interpolation
 - Ctrl+drag on handles mirrors next/prev handle
 - OBJ2VXM updated an improved (both module and tool)
 - Code cleanups
Fixed a bug in the editor widget when single_row enabled (mousewheel scrolling would break it)
Patched up the OpenCV modules to use current vector class
Cleaned up code: messages in engine; implemented time_speed (command: set_time_speed )
Cleaned up indent in vsx_log
Texture now uses gl_state singleton.
Fixed up more gl_state possible problems
Cleaned up vsx_param.cpp; removed unneeded -DVSXU_EXE
Removed a few pointless defines:
  VSX_NO_CLIENT
  VSXU_PLAYER
  VSX_DEMO_MINI
  SAVE_PRODUCTION

Cleaned up some code along the way (formatting, removed comments & printfs)
Fixed regression
Implementing memory barriers and volatile state values for image loaders
Fixed up definitions (cleaner)
Added tentative todos
Cloning of values now handled properly in engine (rather than with artiste's display values). Thus supporting all data types that can be serialized to strings.
Cloning now does not use interpolation.
Various indentation & cleanups.
Fixed regression in component creation in artiste.
New module: particle generator: concentric circles (also moved bitmap blend to bitmap modifiers)
Fixed regression in parameter cloning. Added example in engine parameter handling for "help" command.
