Mupen64 Input Plugin doesn't support external hosts

[OhmGeek]

The C plugin uses TCP sockets, and segfaults when an external host is used (e.g heroku). It only seems to work with localhost.

Some way of properly resolving domain details through a DNS would combat this (e.g. using libcurl)

Alternatively, a more reliable technology such as Rust might be suitable to implement the c method, using easier to interface libraries. Thoughts?

See #25 for a more concrete solution. We should stick to using C for now, and try to avoid external libs if possible for now.
