* gtkfilesystemmodel.c:
- Disconnect signal connections when appropriate.
- Listen to ::roots-changed on the file system
- When the last reference count on a child is
removed, queue an idle to unload the parent.
* gtkfilesystemgnomevfs.c
- When URI's outside of file:/// are acessed,
add toplevel URI's to the list of roots.
- Improve display name computations
* gtkfilechooserentry.c: Don't complete on empty
file parts; free stored folder when base directory
changes.
* gtkfilechooser.c: Fill in some docs.
