Bug fixes and updates

*Added new filter (Sobel and RGB video composite)
*Changed blur filter so that works in YUV space
-This increases performance by reducing the number of operations it has
to perform
-This also eliminated a separate render pass by incorporating the YUV
to RGB conversion into the bluring process
*Reduced number of FBO's created from four to three
*Renamed some files for consistency
*Updated project settings to point to correct storyboards
