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 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.

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.

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.

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.

Added a minimum # of packets to read in the FFmpegReader, which really helps utilize the multiple threads... and improved performance by 27% overall.

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.

Fixed seek method to fallback on both streams, if one stream fails to seek. This fixes MP3s... which have a video stream, but only a single video packet. Also fixed the CheckWorkingFrames method to better determine when a frame is completed.

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.
