As requested by Christian Werner/François Vogel and others: Undo many None -> 0 changes, in order to reduce the probability of merge conflicts with other branches.
Remark: Many usages of "None" in Tk are wrong, "NULL" should be used in many places where pointers are referenced in stead of XID's. Those places are corrected.
