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.

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!

Fixed many audio issues with the FFmpegWriter. Planar formats were not being handled correctly. Framesize was also wrong on some formats. Also, added a new method to a Frame to fill with audio silence. Lastly, cleaned up some unused imports and C++ warnings.

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 GetQImage method to get a Qt QImage object from an openshot:Frame object. Also refactored the video playback code to use this new method.

Fixed some major issues with the frame mapper. openshot::FrameMapper is now fully multi-threaded. Fixed a bug in calculating the # of samples on a frame (to always be evenly divisible by the # of channels).

Added new method to frame, to change the size of the audio container. Fixed audio resampling inside the FrameMapper. Fixed many memory leaks related to AVFrames (still have a few more).

Added new cmake options to set the quantum depth of the installed ImageMagick library... so libopenshot knows how to properly scale color bit depth.

Replaced all copyright and licensing to reflect AGPLv3 license. Also, added a bad ass version header, which is now integrated into CMake as well. A single place to indicate version and ABI/API compatibility.

Added extra start frame to each chunk in the ChunkWriter and ChunkReader, to make sure every chunk can "stoke" the audio samples from the previous chunk. Also, added additional example code for an openshot::Frame.

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.

Fixed a big bug with the Swig wrapper, to correctly match the typemap of the tr1::shared_ptr, and then removed the GetFrameObject method, since it's no longer needed.
