	* app/gui/themes.[ch]: split out function themes_apply_theme()
	from themes_init(). Connect to "notify::theme" of gimp->config and
	change the theme in the callback. Added themes_list_themes().
	Added "const gchar *theme_name" parameter to
	themes_get_theme_dir().

	* app/gui/gui-vtable.c (gui_get_theme_dir): changed accordingly.

	* app/gui/preferences-dialog.c (prefs_dialog_create): enabled
	theme selection on the "Interface" page. Still has many issues
	(like using a conceptually wrong method of theme changing ;-)
	but it won't get fixed if we cannot change themes on the fly...
