More curves view improvements for clip editor:

- Renamed graph_jump_to_current_frame to graph_center_current_frame
  which makes more sense.
- Curve view now can be locked to time cursor (Lock to Time Cursor in
  Display panel or L button in curve view). Not sure if offset from
  locked position will make much sense here.
- Added hotkey for solving -- Shift-S.
