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

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 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!

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.

Added pool of software image scalers to the FFmpegWriter / encoder, and removed OMP critical section. Also, refactored some audio and video codecs, and changed "resize" to "scale" for speed improvements.

Fixed a huge bug where the FFmpegWriter was not scaling colors to 8 bit, and that would crash on certain colors being used in an image. Also, added a new, experimental waveform visualization to the encoder.

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 the ability to specify the image type and scale of any frame when calling the Save() method on a frame. This makes it easy to save any frame as any image type at any size image... very useful indeed.

Fixed the audio resampling by adding a new class called AudioResampler, which maintains state between calls to the JUCE resampler. Maintaining state allows JUCE to remove the discontinuities between the frames, and removes all the pops and crackles.
...
This is a major commit, and changes many things, including build scripts, new classes, and how the encoder works.

Refactored FFmpegReader code a bit, fixed many, many memory leaks, and many valgrind errors. Now the memory seems very stable, and the seeking and stream walking seems very solid.
