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

Added a Sleep.h header, which defines an OS specific sleep metho.

Fixed a big audio regression, with a buggy isnear() function, which did not take into account the amount of frames between the sample locations.

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.

Fixed a really huge audio issue, related to audio timestamps, gaps, and also mono vs stereo issues. This is the best audio support I've accomplished thus far. =)

Fixed a big audio bug, where varying timestamp values on low precision audio timebases (i.e. 1/1000) would leave small gaps in the audio wave. Also, fixed a few issues related to sample_rate getting lost between the reader and clip and timeline objects.

Lots of debug code with some experimental audio PTS code, to adjust for small gaps in timestamps.

Fixed the FFMpegReader to discard the first audio and video frames it finds after a seek, since they sometimes are missing information. This fixed many issues with the time mapping curves and audio reversing and fast forwarding.

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. =)

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

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.

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 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.

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.

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.

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.

Replaced last_video_frame and last_audio_frame with a single last_frame variable, and refactored some related code. This fixes a big audio seeking bug.
