Visual indicator when editing a read-only file

Description

Split off from OC-29:

It would be nice to present some sort of visual notifier (ie, a lock icon) to the user whenever the user is editing a read-only file. (We don't need to take the extreme step of disallowing changes in the UI, because the user can usually use "Save As" to save a copy.)

This is probably pretty low-priority.
