* thunar/{thunar-file.c,thunar-file.h}: Replace
	  thunar_file_is_desktop() macro with a function that
	  recognizes the xdg user Desktop folder. The old macro is still
	  available for glib < 2.14.0
	* thunar/thunar-private.h: Add macros to better support
	  GUserDirectory and an array containing the xdg user dir defaults.
	* thunar/thunar-{launcher.c,shortcuts-model.c,templates-action.c}:
	  Address to the right Desktop and Templates directories.  Don't
	  list templates in submenus if the templates dir points to $HOME.
	* thunar/thunar-shortcuts-model.c: Creation and translation of
	  links to some xdg user dirs in the sidebar in case of unexisting
	  ~/.gtk-bookmarks. Entries pointing to $HOME are disabled.
	* thunar/{thunar-shortcuts-model.c,thunar-private.h}: Add
	  _thunar_get_xdg_user_dirs_locale() to translate the xdg user dir
	  names (package xdg-user-dirs needed for that).
	* thunar/thunar-stock.h: Add icon name for normal directories.
	* thunar/{thunar-window.c,thunar-window-ui.xml}: Add new menu
	  entries, hide the ones related to unused directories and
	  translate their labels. Entries pointing to $HOME are disabled.
