* gedit/gedit-help.[ch]:
	* bindings/python/gedit.defs:
	
	Changed the gedit help helper function to use gtk_show_uri with
	the ghelp scheme instead of gnome_show_help. Using "gedit.xml" as
	the name generates a deprecation warning but will translate to "gedit"
	which will properly show the help to prevent regression for third party
	plugins.
	
	* plugins/snippets/snippets/Manager.py:
	* plugins/externaltools/tools/manager.py:
	* plugins/spell/gedit-spell-language-dialog.c:
	* plugins/sort/gedit-sort-plugin.c:
	* plugins/time/gedit-time-plugin.c:
	* plugins/spell/gedit-spell-language-dialog.c:
	* gedit/dialogs/gedit-preferences-dialog.c:
	* gedit/dialogs/gedit-style-scheme-dialog.c:
	
	Adapted plugins and gedit core to not use "gedit.xml" as the help name.
	Changed to use NULL since they all want the default.
