Summary: Potential AV in vgetargskeywords

Initial Comment:
If you are dumb enough to do what I just did, pass a 
dictionary with non-string keys to 
PyEval_CallObjectWithKeyWords, you may cause an access 
violation in Python (if the call ends up going through 
PyArg_ParseTupleAndKeywords).  The problem is in the 
section of vgetargskeywords which checks for 
extraneous keyword arguments: it does not check to 
make sure PyString_AsString(key) succeeded.  Attached 
is a simple patch.
