[Bf-python] Proposed BPyAPI Additions.

[Willian Padovani Germano]

Hi, Campbell

Python dictionaries do it, so it's a good place to start looking for 
ideas. I just saw the error msg here (function dictiter_iternextkey ) :

http://svn.python.org/view/python/trunk/Objects/dictobject.c?rev=52550&view=markup

Will spend some time on this weekend, to learn more about the possibilities.

It's important but probably not a show-stopper. If we can't find a good 
way now, it can be done later, as long as the docs clearly tell users 
not to add/remove objects inside loops.
