 During signup, the original username is lost if it contains any unusual
 characters because of the sanitize_user() call. This patch restores the
 username so the signup page shows the original username again. The signup
 form will display an error as well allowing the user to modify it.

 The current behaviour returns a modified but acceptable username. Some
 users won't notice and create that user then get angry when they realise
 it has changed.

 This patch also adds the original username to the $result array passed to
 the "wpmu_validate_user_signup" filter.
