more IDL

[Tom Tromey <tromey creche cygnus com>]

I put up a new "release" of my proposed CORBA interfaces:

   ftp://ftp.cygnus.com/pub/tromey/gnome-idl.tar.gz

New stuff:

* Some naming cleanups
* GnomeEventManager interface defined
  This is a generic event manager.
  If we like the standard CORBA one better, we should use it instead...
* GnomeIterate module separated out; provides generic interface
  to iterators

Enjoy,
Tom
