The list from Call.py was in visit_Call. Keywords is a list but it wasn't being checked before. We will need to do more checking of keywordargs later

Fixed assigning vars in a for statement. This fixed augassignments becuase it moved where things got added to scope.
Merge pull request #53 from daviis/visitAugAssign
