	Added API to explicitly register dynamic menu items hierarchies.
	Fixes bug #170623.

	* app/core/gimp.h: added "GSList *plug_in_menu_branches".

	* app/plug-in/plug-in-types.h

	* app/plug-in/plug-ins.[ch]: added API to register plug-in menu
	branches, just as for locale and help domans. Cleaned up handling
	of locale and help domains.

	(plug_ins_exit): free the registered menu branches.

	* app/actions/plug-in-actions.[ch] (plug_in_actions_add_branch):
	new function to explicitly add a menu branch action.

	(plug_in_actions_setup): add the registered menu branches to each
	new action group.

	(plug_in_actions_build_path): always strip the untranslated menu
	path from underlines before using it as hash table key or action
	name.

	* app/menus/plug-in-menus.c (plug_in_menus_add_proc): changed
	accordingly: strip underlines from untranslated menu paths before
	passing them to plug_in_menus_build_path().

	* app/core/gimp-gui.[ch]: added gimp_menus_create_branch() plus
	vtable entry to access the new stuff from the core. Renamed the
	functions desling with items from gimp_foo_entry() to
	gimp_foo_item().

	* app/gui/gui-vtable.c: implement create_branch() and add the
	branch action to all existing "plug-in" action groups. Note that
	we don't need to create any menus because that happens implicitly
	when adding menu items.

	* tools/pdbgen/pdb/plug_in.pdb (plugin_menu_branch_register): new
	PDB wrapper to access branch registering from plug-ins.

	* app/pdb/internal_procs.c
	* app/pdb/plug_in_cmds.c
	* libgimp/gimpplugin_pdb.[ch]: regenerated.

	* libgimp/gimp.def: changed accordingly.

	* plug-ins/script-fu/script-fu-scripts.c (script_fu_find_scripts):
	register the menu branches for all included scripts.
