Validator:
* Add NL translations
* Fix validation of extensions on patterns
* Validation of cardinality on address-line elements containing pattern elements fixed
* Ensure that validator creates errors on example urls by default
* Add -allow-example-urls option to the validator
* Fixed issue where when validating with no terminology server and a value set with only an expansion (no compose), the 'inferred' code system wasn't being populated and validation was then failing on a coding with no specified code system
* when validating value sets, use CodeSystem/$validate-code not ValueSet/$validate-code
Version Conversion Fixes:
* add copying of aggregation mode for conversion from 50 to 30
* add test for Observation conversion from 10 to 40
