Potential security issue with people adding a trailing '.' to your domain

[exor674]

If you have domain forwarding enabled, a user can take control of www.sitename.com. (note the trailing dot) and possibly get ahold of the users master cookie, as well as some other pretty vile things.

Adding $host =~ s/\.$//; on line 256 of cgi-bin/Apache/LiveJournal.pm should correct this issue.
