GW: Add T *QPtrDict::operator()()

[Eric Seidel (no email)]

Add the very strange T *QPtrDict::operator()() which is used in kdom:

T *operator()() { T *ret = (T *)impl.current(); ++impl; return ret; }

And is described here:

Eric and I discussed this and agreed it is probably a bad idea to iterate over
a dictionary this way, instead of using an iterator, so better to fix the
caller.

ok, this is an iterator method, nonstandard, but not so bad.

I'd rather see use of this syntax removed than have support for it added to
QDict. But re-request review if it turns out to be too much hassle.

After further discussions on IRC, I think we came to the conclusion that there
is a real need for this... even if it is a little "odd".
