Refactored some of the FFmpegReader audio class, trying to locate the pops and cracks in the audio.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
...
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.

Added in JUCE audio resampling, and have lots of resampling debug code still in place.

Fixed seek method to fallback on both streams, if one stream fails to seek. This fixes MP3s... which have a video stream, but only a single video packet. Also fixed the CheckWorkingFrames method to better determine when a frame is completed.

Refactored FFmpegReader code a bit, fixed many, many memory leaks, and many valgrind errors. Now the memory seems very stable, and the seeking and stream walking seems very solid.

Fixed a bug when seeking, and not reseting the cache's current frame. Removed some debug code.

Replaced last_video_frame and last_audio_frame with a single last_frame variable, and refactored some related code. This fixes a big audio seeking bug.

Refactored the cache class to only apply the max frames against "previous" frames, and allow unlimited number of future frames, to account for different types of files (some which have hundreds of tiny frames, which need large future cache).

All known memory leaks are now fixed, and the memory seems to hold steady when looping through frames for many many minutes at a time. Fixed a bug with av_free_packet, which was breaking after an audio decode. Removed lots of debug statements.

1) Successfully got OpenMP working with the video processing method.
...
2) Added new "processing" flag, to help determine if a frame is being worked on in a thread
3) Added a new cache Display() method, for debugging reasons
