Added GPUImageLoopingMovie to support looping videos
Removed duplicate GPUImageMovieDelegate definition
Bugfix when recording input from two inputs (mismatched timestamps). Now always uses time from first input.
Fixed #import
Improved handling when looping ends
Added shouldRepeat as property on GPUImageMovie to loop movies instead of a separate class
Fixed forceProcessingAtSize: glitches for the bulge, pinch, pixellate, sphere refraction, and centered Gaussian blur filters.
Merge pull request #1003 from jonathanellis/master
