Hi!

This patch is quite trivial and I'd have liked to commit immediately,
though since Stefan is not able to review my patches ATM and since it
has sth. to do with KDockWidgets, I think it's better to post here.

PROBLEM: Some time ago, I implemented a docking property panel for
artsbuilder but until today, it's possible to "close" it and
impossible to show() it again.

SOLUTION: My patch works like the code in kate: Before showing
(aboutToShow) the menu with the "show xxx dockwidget" toggleaction,
put it in the right state.

LITTLE WEIRDNESS: However, I wonder if it's not possible to connect a
"myHideShowStateIs(bool)" signal to a KToggleAction, but the only
thing I see is the "iMBeingClosed()" signal. Seems to me like a good
addition to the KDockWidget API, no?

Shall I commit (it also introduces a string, but IMHO this is
important)?
