Module pubsub
The publish subscribe mechanism used to maintain lists of stuff.
This helps different pieces of code maintain lists of things (eg
wallpapers, categories) and other to express and interest and be notified
when it changes (eg field editors). The wxPython pubsub module is the
base. The enhancements are a list of standard topics in this file.
This code also used to be larger as the wxPython pubsub didn't use
weak references. It does now, so a whole bunch of code could be
deleted.
