Fixing regression from new caching system, to ignore removing frames from certain JSON changes, for example, deletions (i.e. removing a clip/transition).

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.

Adding new CacheBase class. This is the first of many cache related commits, with the goal of building a disk based cache object, to be used by the timeline object if enabled.

Fixed some big performance issues (some which were causing crashes) in effects (Brightness and Saturation), and created a factory class for effects, to reduce redundent code.

Implementing a small memory bug fix with regards to AV_FREE_FRAME and audio_frame. Also adding in support for duration to be set by JSON, to support long videos from openshot-qt.

Big memory leak fixes in FFmpegReader and FrameMapper, and fixed logic in Frame Mapper with regards to special framerate conversions (24, 25, and 30)... which were causing some inadvertent audio drift.

Added 4 new clip keyframes (channel mapping, channel filter, has_video, and has_audio). These are a bit different though, as they are evaluated as boolean (-1 = ignored, 0 = disabled, 1 = enabled). Also fixed some issues with video playback (where it gets stuck in fast forward), and fixed some race conditions when opening FFmpegReader. Also added more debug output.

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.

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).

Smoother translation of scaled images, and much smoother aliasing of edges of scaling (i.e. zooming in / out, panning across)

Fixed some audio popping issues related to audio buffer size and also resampling issues inside the FrameMapper class. Also made the Timeline more hardened, if a reader returns an error requesting a frame.

Fixing an audio popping / video frame flashing issue with the Timeline calculating the incorrect frame from a Clip. Now the timeline correctly rounds the time diff, and determines the correct frame.

Refactored some audio thread code, and improved performance of timeline (by removing a 'omp ordered' statement that doesn't seem needed). Also added some performance improvements in Clip and FrameMapper classes (if the frame is the same as the source frame... just use the source frame)

Flipping alpha channel values. It was brought to my attention that the meaning of alpha was opposite of what was being used. So, sorry if this breaks some things, but better to get it fixed quickly, and for the value to make sense.

FIxed an issue with audio only files with no default height/width set. Also added improved performance when mixing many audio only files (skipping the image processing)

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 some big issues with time mapping and thread safety. Lots and lots of crashes were fixed related to this. Mostly dealing with an incorrectly sized AudioSampleBuffer when trying to combine multiple frames.

Added wave_color to Clip's JSON properties. Also fixed a bug with adding effects from a JSON diff. Made the background color of a wave visualization transparent, and made the wave graphic come before the effects are processed, which allows the wave to be faded, animated, etc...

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.
