Add multiple access rules capabilities

Under the Administer->access control->access rules->add rule menu

Feature Request #1:
It would be nice to be able to select multiple "Return Types" when entering a rule, such as deny "evil" from Username and E-mail, or Username, E-mail and Hostname. It's currently implemented so that only one choice (Return Type) can be selected at a time. So you must repeat the deny "evil" operation again for each additional Return type.

Feature Request #2:
It would also be nice if you can load a file of words (comma or space separated) to block them from Username, E-mail or Hostname rather than having to type them one by one. It would alleviate the pain of entering so many words manually. This would be useful when preventing the user from entering bad words as part of an E-mail, Username and Hostname.
