In Query Properties Dialog can be set properties like
distinct values and limit.
To open choose Edit\Query Properties.

Steps of implementation:
- Add new slot to Edit menu (menubar.xml): delete the slot of distinct values,
  because it can set in this dialog too
- Separate LimitBox class from limitboxcontroller.cxx (LimitBox.hxx\cxx)
  With it only LimitBox header is included in the dialog source.
- Extend LimitBox class to work with new layout widget (make... and GetOptimalSize())
  and add it to the galde catalog
- Make a class for the new dialog (QueryPropertiesDialog.hxx\cxx) and
  write the .ui file. (querypropertiesdialog.ui)
- Syncronize the two LimitBox (querycontroller.cxx)
