Changes (by sivel):

  * component:  General => Validation


Comment:

 wpmu_validate_user_signup does not currently use validate_username and
 should probably be updated.

 The importers do not use validate_user either.

 Don't commit yet, still researching where else we may need this
 functionality and where these changes could adversely affect current
 functionality.
