LocalTerminologyService should support valueSetVersion paramet for the validate-code operation.

[mmsmits]

Handle the combination of the url and valueSetVersion parameter better.

Currently, the validator (and probably others), will supply a ValueSet url including the version like so:
http://foo.org/ValueSet/bar|1.0.1

However, it's nice to split those (ontoserver even requires it). using the url parameter for hust the uri, and the valueSetVersion parameter for the version. This is an easy adjustment in the validator, however, our LocalTerminologyService doesn't support this yet.
