Large refactor of OpenMP integration (or rather the removal of OpenMP on the Timeline and FFmpeg-related classes). The logic behind this decision, was based on profiling libopenshot and the amount of wasted CPU idle time on all the various threads. The slow code is still synchronous, and all the threads must wait on each other, adding additional overhead. So, removing lots of unneeded threads, and simplifying the underlying Timeline->Clip->FFmpegReader flow. Also, removed 2 calls to QPainter::drawImage, by improving the flexibility of Clip->GetFrame.
