Update submodules: parser (new commits)

parser:
    c15082c Chris Smith <chris@dmdirc.com>
            Make CHANTYPES handling somewhat sane.

            Get rid of weird round-the-houses method of processing, and avoid
            duplicating the value in a map and a field.

            This fixes our handling of servers doing really stupid, theoretical
            things like resetting the CHANTYPES they support. (And by "fixes"
            I mean the parser will keep state, while everything else burns
            around it.)
