PT import: Add MIDI import functionality

Browse Source 
This change adds support for importing all MIDI regions
from a PT session onto a single track.

Unfortunately, currently we don't know how to set the start
offset of MIDI regions reliably, therefore all midi regions
get dumped at the beginning of the Ardour session.
