* Change a number of keyboard shortcuts -- get rid of all the Alt+ shortcuts
  and introduce a few more Ctrl+ ones instead, as well as a number of plain
  single keypresses
* Add Playback menu
* Add time-ruler support for snap to feature, use it in ffwd/rewind
  (rewind still needs fixing)
* restore layer hierarchy window prior to making it work correctly
