Berthold Stoeger dc37ba7758 cleanup: remove QPointer instances
QPointer is a strange "smart" pointer class, which resets itself
when the pointed-to QObject is deleted. It does this by listening
to the corresponding signal and therefore is surprisingly heavy
for a plain pointer. A cynic would say that the existence of
QPointer is an expression of Qt's broken ownership model.

In any case, QPointer was only used at two places, were it was
100% useless: As a parameter to a function and as a locally scoped
pointer. It only makes sense if
a) there is a chance that the object disappears during the pointer's
   lifetime and
b) it is actually checked for null before use
None of which was the case here. Remove.
