[imp] Turn off folder prefix on login screen?

[Edward Glowacki]

Is there a way to turn off the user's ability to set the Folder Prefix
on the login screen?  Our users don't need to be changing that setting,
so I'd like to hide that and just use what's set in the
horde/imp/config/servers.php file.

Thanks!
