0.2 release - now using GPU, gaussian blur and body indexing!

Here's the new version of obs-kinect, using OBS shaders to process things on the GPU instead of the CPU, allowing to use some gaussian blur on the filter texture to improve results.

Changelog:

• This plugins now relies on shaders to use GPU power instead of CPU power.
• It's now possible to use blur passes to improve filter effect.
• Previous filtering and crop options disappeared (since they're no longer required).
• Added body green screen filter (based on Kinect body detection).
