ENHANCEMENT: Change to TreeDropdownField, giving it filtering behaviour as described in ticket http://open.silverstripe.org/ticket/3007 . Its disabled by default for legacy compatibility, but enabled for HtmlEditorField so that link editor is filterable for local links, via an extra boolean parameter on TreeDowndownField.
