In inspector panel, dim disabled settings

Currently properties can be hidden based on object properties. Issue: completely hiding several property controls based on a single toggle is potentially confusing/annoying, especially for toggles that the designer might frequently toggle to compare before-after results.

Add dimming to properties in inspector panel that are disabled with a master toggle or similar, and disable any controls that are affected,

Implementation proposal is to add conditional "DisableIfEqual" etc. to parsing of metadata.xml file, so properties can be easily disabled.
