commit 8c5744bca705a0895bd51c966a30171ee2bab43a
Author: Marisa Kirisame <marisa@sayachan.org>
Date:   Tue Sep 29 23:10:31 2015 +0200

    miniupnpc API version 14 changed the upnpDiscover functions, adding an argument for TTL (should default to 2)
    this enables support for that should the build system have that specific version installed, the miniupnpc bundled in the project is unchanged
