[IronPython] How to make a gtk event?

[Dino Viehland]

Oh, reading comprehension fail...  as long as you don't want it statically declared 
(e.g. it's only ever accessed from Python) then there's a sample pyevent.py in 
the Tutorial which does this. It's just an object with __iadd__ / __isub__ and a 
list of handlers to dispatch to.
