Fix: Unsigned values as parameters (#535)

* Parse uint parameters in client code

Server and client generated code correctly support uint types, but using
uint in client code causes a runtime error. This adds the full
complement of uint types to the parameter parser.

Fix: issues/521

* Parse int16 parameters in client code

All of the other int types are covered by `primitiveToString`; this
completes the set.
