indicate required fields with asterisk

[ndushay]

• add asterisk to indicate required field to:
  • profile metadata: (tests added)
  • resource template metadata: rt id, resourceURI, resourceLabel, author
  • property template: propertyURI, propertyLabel, type
• some small refactoring of existing tests to improve readability (indenting was messed up on one)
• added tests that should have gone with don't display undesired attribs in app and don't put them in the JSON #166

Fixes #190
