Fix for problem importing modules in packages in Pymacs.py (0.12)

[Syver Enstad]

The point being recursing to the "lowest" level to get the actual
module.

This fixes the problem I was having with importing modules like 
Emacs.extensions.

>From pymacs.py, first is new code, second is original 0.12 version
