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.

Added new CacheDisk class, which caches frames to the hard drive, dramatically speeding up preview speeds, at the expense of IO operations. New unittests for caching framework. Fixed a few bugs with Frame constructor, which was causing invalid # width & height. Integrated JSON into the cache framework, to quickly share the state of the cache (including ranges of cached frame numbers). Fixed a bug where some Timeline frames could have no audio samples.

Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false). This allows debug output from all classes and functions, without any duplicate code. Also added some additional debug output for video playback and audio readers.

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.

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.

Windows now passes most unit tests. Added header macro to assist on passing correct test media paths to unit tests. Also added a new info parameter has_single_image, which is used to optomize the frame mapper class for images with long durations.

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).

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.
