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.

Improved changing Reader() on the QtPlayer class, and made many thread safety improvements for the FrameMapper.GetFrame method. Also improved the destructors and Close() methods of FFmpegReader and FrameMapper. Some audio-related bug fixes also, related to audio playback.

Fixed a crash when stopping the QtPlayer class (the cache thread was not being correctly ended, and the audio timeslice thread was not being ended). Also fixed a crash when closing the openshot-player executable.

Removed Cache::Exists method, which created all sorts of havoc when being called in quick succession (basically a frame might exist a split second before calling Cache::GetFrame, but then be missing when GetFrame is called).
...
Next Syntax:
frame = Cache::GetFrame(...)
if frame:
....
Also, fixed some issues with MP3 files having the wrong video length detected, and a few other minor issues.

Replaced ImagMagick with QImage on almost all key methods and classes. Reprogrammed all effects and the entire rendering pipeline to use QImage and QTransforms, primarily for increases in speed and stability. libopenshot is more than 10X faster on many of the most CPU heavy tasks. This was a huge change, and still has a few minor issues relating to BlackMagick Decklink and Text rendering.... which should be resolved very soon.
...
Also, much work has been done on memory management / leak detection, and optimizations with multi-threading... including a new thread cacher class used by the video playback (which is smoother than ever).
