Allow "touch" edits in AutoWikiBrouwser, the way touch.py does.

I am working lately with categories on Commons that rely partially on Wikidata status (see commons:Category:Wikidata_related_maintenance ) and the maintenance categories do not refresh automatically when wikidata item is changed, so one has to always "touch" items in the category before proceeding. A tool to do it more easily than python would be great.
