Add Anthrochat, Furnet to network list

Let's try this again, properly this time:
Reversed the superfluous synIRC changes from my previous pull request and merged upstream commit so this should finally merge easily. Apologies for the earlier inconvenience.

From my previous pull request:
I added two networks: Anthrochat ( http://anthrochat.net/status/ ) and Furnet ( http://furnet.org/ ).
These are two medium-sized IRC networks tailored at the on-line "furry" community.
