Large refactor of Timeline, TimelineBase, ClipBase, and Clip, to allo…
…w a Clip access to the parent timeline instance (if available), and thus, certain properties (preview size, timeline FPS, etc...). This allows for a simpler rendering of Clip keyframes (during the Clip::GetFrame method), and a simpler Timeline class, that can change the preview window size dynamically and no longer requires a Singleton Settings class. - Also removed "crop" from Clip class, as it was never implmeneted correctly, and we have a fully functional "crop" effect when needed - Added caching to Clip class, to optimize previewing of cached frames (much faster than previous)
