Correct underlying integer type of enum TokenKind 

This matches up the underlying type against the actual storage type 'unsigned
short' and lets us get rid of some casts while we're at it.

Effort is made to keep this building in pre-C++11 but as with other features
Token will be less efficiently packed in in legacy configurations.
