    lua: Allow proto:register_heuristic to be used on multiple list names

    In the C API, one can register a heuristic for the same protocol on
different
    lists by specifying another unique short_name. This is impossible in the
    lua API, as the protocol name is used as the short name itself.

    This change fixes that by creating an unique shortname composed of the
    protocol name and the target list name.
