Several bugs (AFAIK not filed into tdf bugzilla) fixed.

Remaining problems:

When some filter clauses go into WHERE and others in HAVING,
they are always logically ANDed (it cannot be any other way),
but that is not communicated to the user in the UI.

Some things left undone:

* DatabaseDataProvider (and its users?) needs to be updated
  to be HAVING-aware, too.

* Form-based filter (.uno:FormFilter) not HAVING-aware
  it reads the current filter in function
  svxform::FormController::setFilter
  in
  svx/source/form/formcontrollers.cxx
  That's one place that needs to be updated.
  The other place is the one that applies the filter.
