UPnP/NAT-PMP support

[jah]

Would allow firewalled users to dcc share files without having to manually open ports. Would make the process seamless.
Transmission's implementation is BSD licensed and written in C, if you could use that:

Otherwise, if you're want to do it from scratch, the NAT-PMP (for Airport routers) spec is here:

and a possibly useful UPnP resource is here:

Awesome! Thanks for the link. This is something I have been wanting to add, but never found a library to use.

Fixed in [3505].
