Part 1 of loading 2.X sessions; some things work, some things don't, hacks a-plenty.

LOADING 2.X SESSIONS WITH THIS COMMIT IN PLACE WILL (PROBABLY) CORRUPT THE .ardour FILE,
MAKING THE SESSION UNLOADABLE ON 2.X AND LOSING INFORMATION.

So don't do that unless you make a backup of the session file first.
