. Fix for AWC-693 - Added evaluator so the user cannot try to Take Ownership of a locked item

. Fixes for AWC-640 and AWC-457
  - Company Home, Guest Home and My Home links now disable/enable depending on the user permissions on the respective locations
  - Guest can now longer see Company Home link if they do not have access (which is the default)
. Company/Home/Guest link toolbar no longer highlights the selected item (as it is not the only way to navigate to it)
