Fix for filter ordering on joins and CDD, wasn't filtering properly on
'label'
Partial fix for CDD in list filter not showing 'all' option.  Got it
working so it says 'please select', but need to work out how to make it
say 'all' in the filter context.
Fixed issue with CDD 'all' vs 'please select' when used in filters.  Had
to add a filterSelectLabel() method override, and move the logic into
_getOptionVals().
Ooops.  Fixing little logic problem with last commit, for showing Please
Select vs All in CDD filters, and still getting it right in form view.
Fixed potentially nasty issue with new group canEdit(), which was
returning $this->canView instead of $this->canEdit.  Don't think it's a
big enough thing to force a 3.0.7.1, but could be.
