* thunar-vfs/thunar-vfs-uri.{c,h}: Add functions to ease the handling
	  of URI lists, specifically to automatically parse and generate
	  string representations of URI lists that conform to the
	  text/uri-list mime type.
	* thunar/thunar-location-buttons.c
	  (thunar_location_buttons_drag_data_get): Use new ThunarVfsURI list
	  handling functions instead.
	* thunar/thunar-favourites-model.c
	  (thunar_favourites_model_file_destroy): Handle the case where a
	  directory referenced by a favourite disappears from the backend media.
	* thunar/thunar-favourites-model.c
	  (thunar_favourites_model_file_changed): Remove a given favourite if
	  the system notices that the favourite's file no longer refers to a
	  directory.
	* thunar/thunar-favourites-model.c(thunar_favourites_model_init): Do
	  not re-add favourites initially, that do not refer to a directory.
	* thunar/thunar-favourites-model.{c,h}: Add a new method
	  thunar_favourites_model_add(), which is used by the
	  ThunarFavouritesView to add new favourites to the list and
	  automatically sync the changes with the Gtk+ bookmarks list.
	* thunar/thunar-favourites-view.c: Handle "text/uri-list" drops,
	  adding new favourites as appropriate. Add note, that the initial
	  idea is based on the GtkFileChooser written by Red Hat for Gtk+.
	* TODO: Remove the 'text/uri-list'-handling for ThunarFavouritesView.
	  Add item concerning the Trash in the favourites list.
