Details for the issue

When you enter an invalid database name to push to dbhub.io, DB4S tries to identify the branch, but fails due to the invalid URL.

The OK button isn't cancelled, so the user can continue. Obviously this doesn't work, but still throws up 'a weird error' (from the users perspective)

The same is with the branch name - this currently allows non-URL friendly characters, resulting in the above 'Ow - what are you DOING?!!!' error.
