OK. This patch now uses only two connections: one to the maintenance DB, one 
to a user selected one. They are the same at the beginning but can change if 
the user selects another database. If he tries various databases, each 
previous connection is closed before opening the new one unless the previous 
one is the connection to the maintenance DB.

There's no more a connection toolbar. There is now a database combobox 
available on the "standard" toolbar. It is filled at startup. Which means a 
user cannot change his connection to an entirely different server.

Patch attached.
