hideProperties works if in code through other means than FF GUI

[LloydRutledge]

See if hideProperties works even if in code through other means than the Fresnel Forms tab GUI. Examples of such means include text editing the saved file and then reloading in Protégé. It is less likely but still work checking if one can use the individual tab in Protégé to add the hideProperty triples to a lens. If it works then it should be in the documentation and set up for checking in the Fresnel Forms MediaWiki extension.
