Feature request: interface for manually adding users

Hi!

On my webhost (www.dreamhost.com), all email address that are created
are assigned a randomly generated username (m########). As such,
RoundCube doesn't work out-of-the-box for logins. You have to
manually add users to the users table in the MySQL database giving it
the correct username and alias. Being as I don't think there's any
way to get it to auto-discover the real username and I'll have to add
these users manually every time, would it be possible to get some
sort of Admin interface that makes doing this easy inside of
RoundCube? I could write one myself, but I'm not familiar with the
codebase and am definitely couldn't integrate it that well into the
design-scheme of the app. Any thoughts on that?

Thanks!
