- Added new Port classes, code to drive them - Added PortList, which is a filthy mess ATM (nevermind that, it's the interface that's important at this stage) - Added ChanCount, though it isn't very thoroughly used yet. That's the next step.... - Fixed a few bugs relating to loading sessions saved with trunk - Fixed a few random other bugs Slowly working towards type agnosticism while keeping all the former code/logic intact is the name of the game here Warning: Removing ports is currently (intentionally) broken due solely to laziness. git-svn-id: svn://localhost/ardour2/branches/midi@786 d708f5d6-7413-0410-9779-e7cbd77b26cf
