---------------------------+------------------------------------------------
 Currently, Query screen does not allow selecting empty columns.  This is
 important for different types of fields:
  * Lists like ''Version'' and ''Milestone'';
  * Edit boxes like ''Assigned to'';
  * Custom lists and edit boxes.

 Proposed implementation is to use value '''(empty)''' for filtering by
 empty columns.  For lists, value ''(empty)'' should be added as a first
 item.  For edit boxes, it should be allowed to enter string ''(empty)'' in
 the edit box.

 Patch attached.
