moved tooltip stuff to a single call.
also the icon stuff has some problems, since i have to check for both an icon
name and an icon picture, hmmm thinking about it with a quite long chain of
callbacks should still be possible...
but the main roblem is that callwithcallback doesn't seem to work with
properties? (this patch hmm doesn't work)
