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!

Fixed the ApplyJsonDiff function to support effects inside clips, which gets a bit tricky.

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).

Cleaned up timeline class a bit, and refactored some OpenMP multi-threading support. The timeline GetFrame() method can not fully support OpenMP at the moment, due to nested parallel regions in some conditional ImageMagick function calls. Also better protected the openshot::Clip.GetFrame() call.

Added effects processing to a clip, so clips can carry their own independent effects... rather than depend on the timeline. This still needs some refactoring though.

Timeline now supports overlapping clips, and will process them from bottom to top. Only the top layer gets effects applied, which enables overlapping transitions.

Fixed some issues with the Mask effect: correctly serialize the reader property, and correctly load the reader. Added additional debug info for the Timeline class.

Changed default keyframes to set a value on X=1 instead of 0. Fixed Timelines composite function to correctly apply alpha channels to the 1st layer of a frame.

Added virtual pixel handling to all openshot::Frame images. Fixed timeline to correctly distort (had to disable multi-threaded support for now). Fixed correct origin handling or rotations and scaling. Added lots of debug support into the timeline. Fixed a bug where readers with different # of audio channels would crash the timeline.

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.

Fixed some serious issues with the Timeline class, improved the Timeline unit tests to cover more of the code, and fixed a bug with the Clip class... which removed the Reader during closing.

ApplyJsonDiff now clears the internal timeline cache (since things might have changed), and the timelines GetFrame always resorts the clips, to be sure they are in the correct order... not ideal, but better than out of order.

Fixed many issues with the QtPlayer and related classes. Now the VideoRenderer can be passed through SWIG and connected to a PyQt application and handle display signals for each frame. Also, refactored some OpenMP settings into its own header.

Replaced all copyright and licensing to reflect AGPLv3 license. Also, added a bad ass version header, which is now integrated into CMake as well. A single place to indicate version and ABI/API compatibility.

Added JSON change method, which accepts a diff / sync JSON array, and applies the changes to a timeline and timeline associated properties and items. Also fixed many bugs on JSON type checking.
