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.

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).

Refactored out many omp critical statements related to debugging, and made them conditional based on if debug is enabled.

Replaced the FrameMapper's omp task with omp for ordered, and it now runs fully multi-threaded... while still keeping the resampling calls in order.

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.

Added new debug methods, and refactored the ReaderBase and WriterBase to better utilize the base class constructor. Also fixed some FFMpegReader issues related to seeking and determining when frames are actually ready.

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.

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.

Fixed a few more show stopping bugs related to FrameMapper and converting frame rates, and re-mapping audio samples. Integrated in special handling of certain framerates (for pull down support), and Keyframe linear curves for all other frame rates.
