Camera tracking integration

===========================

- Added python method MovieClip.tracking.tracs.add() to add new track.
  Marker for this track is getting created on position (0, 0) and it's
  keyframed to specified frame number.

- Implemented rotation 2D stabilization. It's supposed to be used in the
  following workflow:

  * Set tracks which defines location stabilization.
  * Choose one track which defines orientation.
  * Vector which connects median point of location and track used for
    rotation would have the same orientation along all frames.

  2D stabilization with rotation can be a bit slow.

- Some internal refactor and code clean-up.
