        Return the current Property Manager widget (whether or not its tab is
        chosen, but only if it has a tab), or None if there is not one.

        @warning: This method's existence (not only its implementation)
        is a kluge, since the right way to access that would be by asking
        the "command sequencer";
        but that's not yet implemented, so this is the best we can do for now.
        Also, it would be better to get the top command and talk to it, not
        its PM (a QWidget). Also, whatever calls this will be making
        assumptions about that PM which are really only the command's business.
        So in short, every call of this is in need of cleanup once we have a
        working "command sequencer". (That's true of many things related to
        PMs, not only this method.)

        @warning: The return values are (presumably) widgets, but they can
        also be mode objects and generator objects, due to excessive use of
        multiple inheritance in the current PM code. So be careful what you
        do with them -- they might have lots of extra methods/attrs,
        and setting your own attrs in them might mess things up.
