has_icon_name
Description:
Checks whether or not this has an icon name.
get_icon_name will always return some value, even if this has no icon name set; has_icon_name can be used to tell if that icon name is real or not.
(Note that if has_icon_name returns false, but
has_name returns true, then the name returned by
get_icon_name is this's name. Only
when both methods return false does get_icon_name return a
generic fallback name.)
