IDocument: Simplify permission changes

Browse Source 
Take care of handling file permission changes centrally.

TextDocument had its own, caching implementation of tracking the backing
file's read-only state. Move that into IDocument directly.

IDocument::reload with a permission-only change is not a very
interesting case, but every subclass needed to add handling of it.
Instead, remove TypePermission from the file-change types, and handle it
separately via the now unified checkPermissions() implementation.
IDocument::reloadBehavior already was never called with TypePermission.
