[Bf-python] Proposed BPyAPI Additions.

[Ken Hughes]

Should the scn.objects sequence/iterator (whatever we're calling it) be 
documented in epydocs as its own class?  Seems a bit obscure to have to 
look for the scn.objects attribute to then find out what attriutes the 
attribute has....  and even then, we need to document what the argument 
are to .new() somewhere.

BTW, as per last week's conversation I've removed "None" as an argument 
for .new() and added string checking, for "Empty" right now.  Should I 
go ahead and commit that?
