[Bf-python] Ok, I've made a replacement Vector (CArray) for EMesh

[joeedh]

Since Vector no longers deals with pointers to arrays, I've written a 
replacement list type for EMesh, since obviously we need a list type 
that can work directly on the EditVert/Face/Edge data (see CVS maillist 
post).

Just finished basic functionality.   Now comes the part where whenever 
you remove a vert /edge/face, that vert/edge/face is sent  to CArray (or 
maybe a part of EditMesh) so it's CArray's objects (->co, ->no) know to 
not accept any manipulation of it's values (since obviously the no, co 
arrays of the vert/face is no longer there).

Wrote this in haste, sorry for the confusion.

Oh, and this is only a barebones list type with error-checking, so it 
has none of Vector's nice features.
