Many small improvements, bug fixes, and build system fixes for newer systems that have both qt4 and qt5.

Refactored blackmagic capture example into DecklinkCapture.cpp, and added it into libopenshot. Also, added a new, Main_Blackmagic.cpp example program, which invokes the DecklinkCapture.cpp class.
...
Also, built in a 20 frame buffer into the DecklinkCapture.cpp class, to discard old frames, to keep the memory from filling up.

Integrated more timeline code, such as compositing layers... but they don't work yet

Added delta() to a coordinate, to track the change in unique value on the Y axis. This helps in time mapping, to track how many frames have been skipped.

Added some new methods on the keyframe class, and added some unit tests for the keyframes.

Many experimental changes, including a new FrameMapper that is based on FileReaderBase, and lots of debug code.

Added a new DummyReader, which can be given any framerate, samplerate, width, height, etc... and used in unit tests, such as the FrameMap unit tests.

Started working on the FrameMapper, to correctly map audio samples to the target framerate.

Removed some unneeded methods, due to the previous refactor involving shared_ptr objects. They no longer require some special overloads which "delete" the objects in the cache.

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. =)

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.

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.

Added a FrameRate() method to the timeline, to get or set the fps. Also, added a unit test for that, and refactored some header files to be alphabetical.

A big refactor of the Open() method on Readers, and the constructor of Readers. All resource consuming code has been moved into the Open() methods, so the Clips and Timeline can control them better.

Added Open() to the reader base class, so all readers need to have that method now. This is to allow the timeline to better control Clips and Readers.

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.

Renamed some of the basic clip property getters and setters, and added some simpler ways to get the value of and add points to a key frame.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
...
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.

Added new unit tests for FFmpegReader, which tests actual pixel color values against a test video on 2 different frames. Also, made Seek() method private.

Added some new methods to access audio data: channels, samples, etc... Also, added initial unit tests for the FFmpegReader class, including waveform checking against an actual audio file.
