Updated misc/gui/wxbe with wxPython -> wx changes.

I'd like to be able to sort the bugs by clicking on the various column
titles, but I don't know enough about wxPython to pull it off.  After
wrestling with it for a bit, I realized that I'll only be using the
command line interface anyway, and other people can use the web
interface.  Probably a common feeling, which would explain why the
GUIs feel so abandoned ;).

At any rate, I think the effects of turning the RCSs into classes have
been passed through and stabilized, so my churning should decrease...
