Calculate length_beats of split MIDI regions from 'parent' region.

Browse Source 
This is probably less than ideal, since setting the properties later will
recompute from frames values.  It is, however, slightly more rightish :)

Seemingly correct cases (i.e. where length_beats is correct):
 * Recording a new MIDI region
 * Splitting said region

Broken:
 * Loading a region from XML

Untested:
 * Import
