Removing unneeded std::map which has holding all AVPackets, which was causing a memory leak and crashes.

Added a new optimized constructor to some readers (FFmpegReader, QtImageReader, ImageReader) to not Open() in the constructor, which dramatically speeds up creating hundreds of Readers (i.e. when opening a project). This is really only useful when inflating the reader with Json right after you instantiate it...

Added SetMaxSize for image optimizations in QImageReader and FFmpegReader, which lets the timeline pass down the max size to all clips and readers, so they can optionally optimize the size of images (especially useful for optimizing preview performance). Removed convoluted image scaling code in FFmpegReader, and replaced with simpler version. Also, fixed a few regressions from the new Caching code, primarily a crash when reaching the end of the last clip on the timeline.

Improved detection of missing audio frames, and missing video frames. Also improved logic for giving up on missing frames in general. Also removed some deadlocks related to Seeking (Close() and Open() were deadlocking). The end result is much improved compatability with reading video files.

Adding new dependency: libzmq (ZeroMQ). Adding a new debug logging class powered by sockets and ZeroMQ, to allow a threadsafe way to communicate debug messages to a client application (i.e. openshot-qt). Also, removing unneeded Sleep.h functions. There will be lots more code utilizing ZeroMQ soon.

Making ImageMagick completely optional. This will simplify packaging on Windows and Mac. Also, reprogrammed Display, DisplayWaveform, Save, and Thumbnail methods, which are much faster now (using Qt).

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.

Fixed delay with certain types of audio files which also contained a video stream with a single frame. Added some good 'dont get stuck' logic when checking for gaps in video/audio timestamps, etc...

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).

Many improvements to FFmpegReader, including
...
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

Fixed a bad seek bug, where the FFmpegReader would read until the end of stream looking for a frame. Also refactored a bit of cmake code.

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.

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.

Made some dramatic improvements to the QtPlayer classes, especially audio / video sync. All of my test files now work correctly, with no audio or video issues! Also, now audio only files also work, and image only files.

Fixed RendererBase to correctly use writePixels, instead of iterating through PixelPackets. Fixed Audio Crash caused by not initializing a JUCE background audio thread. Added an OutOfBoundsFrame exception on the FFmpegReader, when the end-of-stream is detected.
