Do some caching of window title and related UI

This should avoid performance problems related to the window update machinery.
Moreover this fixes a crash introduced by 82808fea when closing a file.

Note that GuiWorkArea::Private already had a read_only_ member, but it
was unused.

Also rename LyXVC::vcname() to LyXVC::vcstatus() since it now contains
directly the UI string to be shown.
