Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

Fixed a regression with audio files and seeking, added a few new methods, and more accurately detect the End() of clips.

Fixed a regression with disabling seek on the FFmpegReader. It runs slower than seeking, but has no artifacts of seeking, and is frame accurate.

Fixed the seeking and cache code to work correctly. Also fixed a huge memory leak with the new AVPicture structs. Now the time mapping works both directions, and with no major memory leaks!

Another huge refactor and lots of big fixes! Time mapping now works... mostly. The jumpy / glitchy images have been solved by copying the AVFrame into an AVPicture, which does not get clobbered on the next decode.
...
Also, added a new frame number overaly (in the top, left part of the image), and a new AddColor() method, to change the size and color of the frame's image...
Padded the end of the FFmpegWriter / WriteTrailer() method, to avoid having a codec ignore the last many frames.

Major refactor to the cache object (again)! It now uses bytes to determine how many frames to keep.

Refactored seek method a bit in the FFmpegReader, to fix some bugs. Also, being changing the cache object again, on how it cleans up pointers. Some debug code is checked in also.

Added new method to adjust the min value of a valid frame number, added a new unlimited cache option, and fixed a bug which was preventing the timeline from calling GetFrame correctly. Now timelines, clips, and readers are working together nicely.

Fixed a regression with the FFmpegReader, to always get frame 1 first, to calucate the PTS offsets, etc... Also, fixed a bug on the timeline, and now i'm 1 step closer to having it all work. =)

Added an example, trying write a timeline to the FFmpegWriter. Not quite working yet though.

Added a Rotate() method to a Frame object. Added new methods on a clip to translate frame numbers (FrameMapper and Time Curves). Now, the Timeline, Clip, and Readers are all working with animation curves. Pretty cool!

Implemented the Close() method, so it closes all clips' readers on the timeline

Refactored constructor() methods on readers again, to call Open() and then Close() methods automatically, to populate the info struct. And moved the GetFrame() call out of the Open() method, because it was unneeded and slowed down the Open() method.

Added some functionality to the timeline GetFrame() method, and build a way to update the list of opened clips, to manage which files are open and closed, etc...

Protected the Open() and Close() methods better, so the FFmpegReader will not crash. Also, made the Open() method public, so the Timeline and Clip classes can control the reader better.

Overloaded Clip comparison operators, to use the Position() of clips for sorthing routines. Also, added the AddClip method, to add clips to a timeline (and sort them by position).

Made the Timeline class inherit from FileReaderBase, which means the Timeline is really just a fancy ready class now. Also, added new unit tests for the Clip and Timeline classes.

Improved the logic to decide which reader to use. ImageReader sometimes hangs when passed "mp4" video files, so we now check for common movie extensions first.

Added a new experimental overlay method to a frame, which composites images from multiple frames, and adds the result to the bottom right side of the image.

Added a new ImageReader class, which uses ImageMagick++ to read image files, and produce openshot::Frame objects.

Enabled multi-threading decoding and encoding with libavcodec, setting the thread_count property. This make a huge improvement in CPU performance, for codecs that support this property.

Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single".

Improved the multi-threaded code, by requiring a minimum of 8 frames to be processed by the reader.
