[IronPython] Importing embedded .py files

Out of curiosity, is there any sort of hook into the engine that would allow
you search for a module on your own?  e.g. a search of sys.path did not find
the specified module, so before raising an import error, we give a set of
registered event handlers a crack at it? I would envision a cancelable event
would be raised, such that the first handler (if any) to successfully find
the module would prevent further handlers from being called.

I would need to take a closer look at the engine interfaces to see if this
would work, but I'd think this would be a relatively minor change (if its
not there already, of course).

This is working except two of the embedded .py files import each
other, so no matter which one I place first, it errors out.  So I
guess I can catch it. lol. It's going to end up being about 60+ lines
of code to import 9 modules into the engine.
Or, I could modify the .py files some more but I prefer not to.
