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!

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.

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.

Fixed some big memory leaks with audio samples and ffmpeg (pprof ./openshot-example "/tmp/openshot-example.30691._main_-end.heap" --inuse_objects --lines --heapcheck --edgefraction=1e-10 --nodefraction=1e-10 --gv

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.

Completely rewrote audio encoding API (old one was depreciated)
...
Integrated new debug output, which makes troubleshooting issues much easier
Simplified the Writer API calls (some methods now get automatically called if needed). Now a few simple methods can write an entire video file.

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.

Switched my simple bitshifting to use the ImageMagick ScaleQuantumToChar() method, which handles all the different bit depths and data types that ImageMagick can be compiled with.

Fixed a bug with bitshifting float color values. ImageMagick can be built with different types of Quantum color values, and Im trying to make libopenshot work seemlessl with them.

Adjusted ImageMagick code to dynamically calculate the quantum depth, and bitshift between that depth and the 8bit colors for FFmpeg.

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.

1) Reduced all openmp to use /2 the available CPUs (for performance reasons)
...
2) Improved detection of pixel format (enabled GIF support.. although it is still flawed a bit)
3) Improved error reporting when video encoding issues happen
