Refactoring the VideoCacheThread to check every frame before requesting it. Adding a new method: Contains() to our cache objects, to facilitate this. Removing cache clearning experimental code from Timeline (causing playback issues). Refactoring PrivatePlayer playback timing code, to calculate an average # of frame difference between audio and video threads, and slowly adjust back towards zero when needed.

Improving performance after working with google-prof, to profile CPU. Calling OMP_MP_NUM_PROCESSORS less often, since it's quite expensive according to profiling. Adjusting Timeline final_cache to match the video caching thread max_frames, so one doesn't clobber the other. Also, fixing an issue with openshot-player, where a video file with no audio skips horribly.

Improvement to video caching thread, to recover from the separation of cache vs display frame #. Also found a mutex that was needed, to prevent crashing when the video thread calls timeline::GetFrame at certain times... colliding with another thread (and independent of OpenMP).

Changing some sleep() calls to usleep(), for more accuracy. This is a bit experimental, and hopefully will work on all OSes.

Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves.

Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)

Added new CacheDisk class, which caches frames to the hard drive, dramatically speeding up preview speeds, at the expense of IO operations. New unittests for caching framework. Fixed a few bugs with Frame constructor, which was causing invalid # width & height. Integrated JSON into the cache framework, to quickly share the state of the cache (including ranges of cached frame numbers). Fixed a bug where some Timeline frames could have no audio samples.

Added 4 new clip keyframes (channel mapping, channel filter, has_video, and has_audio). These are a bit different though, as they are evaluated as boolean (-1 = ignored, 0 = disabled, 1 = enabled). Also fixed some issues with video playback (where it gets stuck in fast forward), and fixed some race conditions when opening FFmpegReader. Also added more debug output.
