dbhub: Automatically generate a file name to save a database under

Browse Source 
When fetching a remote database automatically generate a file name to
save the database as instead of asking the user for a path and name.

Also add a preferences option to set the directory for all cloned remote
databases.

This is obviously a trade-off: on the one hand this makes opening remote
databases simpler (it's just a double click), on the other hand it takes
control away from the users. The main reason for doing this, however, is
to indicate to the user that the cloned databases are going to be
controlled by DB4S. We have to keep track of the local databases in
order to update them from the right place, push them back to the right
place, etc. And because the local copies are under DB4S control we don't
want the user to move, rename, or delete them.
