Etienne Dechamps 2bb567c6a3 Add a new optional dependency on the miniupnpc library.
The miniupnpc library is a lightweight UPnP-IGD client.

http://miniupnp.free.fr/

Contrary to other libraries, this dependency is disabled by default.
This is because the library is somewhat obscure and is only tangentially
useful, so enabling it by default would probably annoy most users.
