* This rather heavily reworks how database shutdowns works. It adds much more intelligent shutdown, tracking who is using the database, being able to mark a database as "offline" and waiting for users of the database to disconnect before it shuts down.
* Also removed the variables for the database name and DB user name, setting them statically now.
* Created Database->shutdown() to more kindly stop a local database server.
* Added 'check_db_in_use_states()' to anvil-daemon to clean any stale entries marking a database as in use.
