GLMixer Code

Ensure compatibility with different versions of ffmpeg lib (avcodec & avformat).

Fixed memory management (use av_free instead of free), and adapt code to avoid DEPRECATED avcodec and swscale functions.

No need for QElapsedTimer which is not available in all versions of Qt : using QTime is enough.

Improvement of the recording of the output: implementation of a THREAD for performing the avcodec encoding, using a queue of pictured filled from opengl and encoded in parallel. Added warning for low frame rate recording.

Added the FLV video format for recording output. Added a check of synchrony success for recording, although a real solution with dynamic fps during recording or re-encoding of the movie with good fps would be better.

Added the flag "playing" in the .glm session format (i forgot that one could save a file with a source stopped, and that this satus should be restored). Added "file size" info in the property manager of Media source. Restored Crtl-F and Ctrl-C shortcuts to fullscreen and Capture source.

minor fix of error dialogs in frame capture.

Added action "save frame capture" and modified a bit the creation of frame capture source (mainly the terminology). Small changes in menu and toolbars (created a toolbar dedicated to RENDERING) and added a button for saving captured video (in prevision of start/suspending of recording).
