* STATUS: Big status update.

	* TODO: Create a TODO list.
	* configure.in.in, Makefile.am, tdb/: Remove TDB entirely.
	* libxfce4menu/libxfce4menu.h: Clean up.
	* libxfce4menu/xfce-menu-and-rules.{c,h},
	  libxfce4menu/xfce-menu-not-rules.{c,h},
	  libxfce4menu/xfce-menu-or-rules.{c,h},
	  libxfce4menu/xfce-menu-standard-rules.{c,h},
	  libxfce4menu/xfce-menu-rules.{c,h}: Remove all the XfceMenu*Rules
	  classes. Replace them with one very simple XfceMenuNode function.
	* libxfce4menu/xfce-menu-directory.{c,h}: Replace the filename string
	  property with a GFile file property. Replace
	  xfce_menu_directory_get_filename() with
	  xfce_menu_directory_get_file() and remove
	  xfce_menu_directory_set_filename(). Fix typos in the signal
	  installation code.
	* libxfce4menu/xfce-menu-item-cache.c: Remove all TDB related code.
	  Avoid memory leaks when creating new items (same patch as went into
	  the old trunk a while ago, bug #3812).
	* libxfce4menu/xfce-menu-item-pool.{c,h}: Update
	  xfce_menu_item_pool_apply_exclude_rule() and
	  xfce_menu_item_pool_filter_exclude() to use a GNode instead of an
	  XfceMenuRuleStandardRules.
	* libxfce4menu/xfce-menu-item.{c,h}: Accept URIs as input to
	  xfce_menu_item_new() and convert them to paths using GFile.
	* libxfce4menu/xfce-menu-merger.{c,h}: Implement the missing merging
	  and moving code. Fix a lot of bugs in the code. Never access
	  XfceMenuNodes directly, always use xfce_menu_node_tree_*()
	  functions.
	* libxfce4menu/xfce-menu-node.{c,h}: Add more xfce_menu_node_tree*()
	  functions. Simplify the code. Add support for matching
	  Include/Exclude/And/Or/etc. rules against XfceMenuItems.
	* libxfce4menu/xfce-menu-parser.{c,h}: Minor cleanups.
	* libxfce4menu/xfce-menu.{c,h}: Change the first parameter of
	  xfce_menu_new() to GFile. Remove all the parsing code. Use
	  XfceMenuParser and XfceMenuMerger in xfce_menu_load(). Update all
	  the menu loading code to use GNode DOM trees. Replace the filename
	  property with a GFile file property. Still waiting to be implemented
	  again is the layout stuff. Remove functions like
	  xfce_menu_get_directory_dirs() which were not meant for public use
	  anyway.
	* tests/test-display-menu.c, tests/test-menu-parser.c,
	  tests/test-menu-spec.c: Update to the new API. Cleanups.
