Randomize Sectors form: floor/ceiling height controls now have "Offset mode" drop-downs. Available modes are "Raise and lower" (default), "Raise only" and "Lower only".

Consistency, Randomize Sectors form: persistent settings are now saved only when applying changes done in the form (e.g. in the same conditions as in Randomize Things / Vertices forms).
