Subject: [PATCH] Added support for authenticated SMTP. I'm going to do a few
 tests on this tonight. Added 87 new emoji shortcodes. We now have all of the
 Unicode v1.1 emojis covered. Added support for #fid hashlinks. Added the :(,
 :O, :o, and :p smiley codes.

Fixed a bug where the topic data wasn't getting updated after creating a reply.

Added the get_forum function.
Added the get_forum_copy function.
Added the build_forum_url function.
