Support creating databases in schemata other than main and temp

This replaces the checkbox for creating tables in the temporary schema
by a dropdown box that lets you select between all available schemata,
i.e. main, temp, and all attached databases. This way it becomes
possible to create new tables in attached databases as well as move
existing tables between all schemata.
