Comment 6 for bug 1310261

I've started implementing a fix for this. With the below commit, hidden items are now marked italic. This was an intended feature from the beginning, but the wrong keys were being evaluated.

For the second part of this implementation, I'll need to evaluate when items are explicitly hidden in the menu files.
