Fixing invalid cache after editing effect in a clip, and frame accuracy (converting timestamps into frame numbers). This makes frame by frame editing much better.

Fixed many more regressions with audio files not passing cover art to the next frame correctly. Seeking issues, and many related issues to detecting missing frames improved. Also fixed a deadlock in certain seeking cases.

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.

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!

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).

Added new method to frame, to change the size of the audio container. Fixed audio resampling inside the FrameMapper. Fixed many memory leaks related to AVFrames (still have a few more).

Laying the ground work for audio mapping (resampling and changing channel layouts) for the openshot::FrameMapper. This is important for use with the Timeline, that all clips have a common frame rate, sample rate, and channel layout.

Fixed bug in AddImage() method on a frame, to copy the image instead of just pointing to it. This fixed many issues in the FrameMapper as well, which copies images alot.

Added Deinterlace effect. Refactored Wipe effect into Mask effect (which is a more appropriate name). Added an example interlaced.png file. Improved the Mask to accept a 'reader', which can be used for more elaborate wipe animations.
