beautify alias list search parameters

AliasHandler:
- initStruct(): handle __mailbox_username as separate field (needed to
  make it searchable)
- split off a condition_ignore_mailboxes() function (used in getList()
  and getPagebrowser()) to add '__mailbox_username IS NULL' to the search
  condition array. Also, make sure $condition can be an array (preferred)
  or a string with a raw query

list-virtual.php:
- hand over a search array instead of a raw query
