When standing in a parcel it would be helpful to have a graphical indication in the UI if you are able to build/rez.

The icon in the (mini) location bar shows parcel properties, not what is available to you as parcel owner or as a member of a group that has rezzing enabled as one of your group roles.

Suggested solution: Gray out the build button if it is present on the toolbar, just like the Speak button is grayed out if voice is not available.

See test plan in jira.

I also searched the xml files to be sure no other calls to LLAgent::isActionAllowed were being made.
