Camera tracking: initial commit of dopesheet view for clip editor

- Displays dopesheet information for selected tracks, and currently does not
  support any kind of editing.
- Changed regions to use the whole main region for such views as curves and dopesheet.
  This allows to have own panels with tools/properties in this area.
- Active clip is getting synchronized between different clip editor editors in the
  same screen, so updating of curve/dopesheet views happens automatically when one
  changes current clip in one of this editors.
- Panels in toolbox and properties panels are now separated to rely on current view
  mode, but some operators and poll functions still need to be updated.
- Added new screen called "Movie Tracking" where layout is configured to
  display timeline, main clip window, curves and dopesheet.
