Title: Changes to GPUImageVideoCamera GPUImageMovieWriter and minor cleanup.

I made some changes that were necessary for my implementation of this framework. Basically, I need to set the camera frame rate and change the AVCaptureSession on the fly.

In addition, I like the way this framework was modified to allow easy specification of GPUImageMovieWriter's video settings, I thought it would be a good addition to allow the same to be done for audio settings.

I made some other additions to allow for a quick check of the availability of a front-facing camera.

I also did some cleanup, basically adding some newlines to end of some files that were missing them and removing weird ; characters that were at the end of method names in the implementation.
