* Fix update and play limits for play-selection mode when not looping
* Fix playback in loop mode when no selection -- but the GUI update for
  this is still wrong on the flyback
* Various fixes and improvements to making selections, particularly during
  playback
* Draw selection under non-opaque non-scrollable layers, so as to improve
  cacheing
* Show selection limits as text when drawing selection
* Allow user to find missing audio files when loading session
* Cross-fade selections when in play-selection mode -- mostly.  We don't
  cross-fade on a processing block boundary, and unfortunately with short
  selections the selection boundary is quite likely to coincide with a block
  boundary.
