Title: Fixes forceProcessingAtSize: bugs and also allows access to the AVCaptureConnection of a GPUImageVideoCamera

As outlined in this Issue #287 (https://github.com/BradLarson/GPUImage/issues/287), forceProcessingAtSize can cause some undesired effects when used multiple times. This commit fixes these issues.

In addition to this, it is now possible to access the AVCaptureConnection of a GPUImageVideoCamera, which allows for more fine-grained control such as toggling video stabilization, zoom factor, and enabling/disabling the entire connection.
