Proper Auth

[dariota]

Right now, Gambot just checks nicks for authentication before certain operations. There's a number of ways that better user authentication can be done, such as (in descending order of good ways to do it):

• checking the last line of /whois nick for an account name
• checking for auth with NickServ (see here for details)
• user+host pairs, where the host is not in some blacklist of (for example) webchat clients and other such hosts that are not necessarily fixed

Alan also mentioned that he uses "account-info extensions to the IRC protocol", which can also be worth looking into and probably more portable than the above.
