Enhancement: Updated all typestub files to the latest from the typeshed repo.
Bug Fix: Fixed issue that caused public member variables with annotated Literal types to not accept a literal assigned value.
Bug FIx: Fixed several bugs in type checker's logic that caused some type violations not to be reported.
Bug Fix: Changed Tuple (with no type arguments) to default to Tuple[...] rather than Tuple[].
