Assert on batch/* commands.
0.1.369
Throw error on illegal database name.

But verify against list of known commands that require a --database
option so the error is not spuriously thrown when running commands that
do not require a database (interactive mode exit for example).
0.1.370
Work on the server/database validation logic.

Improvements to unknown command handling in interactive console.
0.1.371
Update dependencies.
