Adds the `net.SetConn` function. It sets the current connection
to the given one. This function is explicitely only used to
provide network mocking for unit tests.

Testing code provides a mock implementation of the `net.Conn`
interface and passes it into this function. This allows the
entire IRCB protocol API to be used, without having to open
a connection to an actual server.
