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 many misc Windows runtime errors and memory-related crashes. Built a few macros for common FFmpeg / LibAV functions that change due to version differences.

Improved support for missing frames and invalid PTS (which result in gaps and duplicate frames). Also changed frame number to larger data type, and did some code clean-up and refactoring. Less crashes, and more video support!

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.

Fixed many audio issues with the FFmpegWriter. Planar formats were not being handled correctly. Framesize was also wrong on some formats. Also, added a new method to a Frame to fill with audio silence. Lastly, cleaned up some unused imports and C++ warnings.

Removed exception handling for audio decoding... which sometimes fails when seeking... and it can be safely ignored.

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).

Fixed some major issues with the frame mapper. openshot::FrameMapper is now fully multi-threaded. Fixed a bug in calculating the # of samples on a frame (to always be evenly divisible by the # of channels).

Fixed a huge bug when closing a reader and re-opening it. Added some new unit tests to test for that bug, as well as check the ordering of layers and effects. Improved opening and closing of openshot::Clip->Reader() to better support multiple threads.

Better bounds checking, and support at the end of the video file
Improved debug output, which helped resolve many issues
Implemented the newest audio decoding API (old one was depreciated)
Now support packed and planar audio data
Far superier audio resampling support
