* docs/design/overview.xmi: All navigational UI elements in a
	  ThunarWindow now implement the ThunarNavigator interface, which
	  defines the "current-directory" property and the "change-directory"
	  signal. See the ThunarNavigator gtk-docs for details about the
	  behaviour.
	* thunar/thunar-navigator.{h,c}: Provide source code for the current
	  ThunarNavigator interface.
	* thunar/thunar-side-pane.{h,c}, thunar/thunar-favourites-pane.c:
	  Changed to use ThunarNavigator instead. ThunarSidePane is currently
	  an empty interface.
	* thunar-vfs/thunar-vfs-uri.{h,c}: Add a thunar_vfs_uri_to_string()
	  method, which transform a ThunarVfsURI into a file:// uri.
	* thunar/thunar-location-bar.{h,c}: Provide source code for the
	  ThunarLocationBar interface, which extends the ThunarNavigator
	  interface. The ThunarLocationBar interface does not add anything new
	  currently, but that will change in future revisions.
	* thunar/thunar-location-buttons.{c,h}: Add location path buttons
	  implementation of the ThunarLocationBar interface. The layouting
	  code was mostly copied from gtkpathbar.c, which was initially
	  written by Jonathan Blandford. The implementation is not complete
	  yet, and the layouting code is still very buggy.
	* TODO: Add a bunch of TODO items for Thunar 1.0.
