edit-mailbox.php

- fix: put the values the user entered in the form again if an error was
  detected (instead of showing the form completely empty)
- fix: do not check for password length when password is not going to be 
  changed (empty password field).
  Thanks to Danilo Montagna (dmontagna) for pointing this out!
