#17 Bind to specific local address for IRC connection

[TmowhrekF]

Dirt should have a configuration option to specify the local IP address or hostname to bind (outgoing) IRC connections to.
The default setting should be * (any address).
This is useful for machines that have several IP addresses and/or are using virtual hosts.
A command line parameter to override this setting would be a good idea as well.

Note that this will not change the "listening on 127.0.0.1 only policy".

[TmowhrekF]

Bumped the priority.

The following example illustrates the plan:

[bind]
address=192.168.0.8
port_range=5000-5999

Where either can be empty or 0 to let the operating system decide the local address and/or port.
Again, this goes for the IRC connection. The Dirt server will still listen on 127.0.0.1 and allow connections from 127.0.0.1 (localhost) only.
