David's commit: the connections view was not listening to the changes in connection status, so unless a service changed status, the change in connection status didn?t get updated

PlatSim-related launch wizard changes: (1) Remember last connection created and offer this by default in the Select Connection dialog; (2) Immediately open New Connection dialog if debugging and no connections exist; (3) Split out SelectConnectionDialog; (4) Fix some wording in Select Connection dialog since this is not always an error situation.
