and GladeEditorProperty to manage/edit a list of strings that can be translatable.
	  This property editor uses a treeview and supports reordering of rows with Drag'n'Drop
	  as well as deletion of rows using the 'Delete' key. Every row can have individual
	  i18n information set via the common i18n dialog.

	* plugins/gtk+/glade-gtk.c, plugins/gtk+/gtk+.xml.in: Add GtkComboBoxText support
	  to Glade and use the GladeStringList boxed type to edit the list of translatable
	  items.
