There was already a basic theme which uses the Gathering of
Tweakers smileys, but a couple of smileys weren't present, and I ran
into compatibility issues with a lot of MSN users, because they often
use a lot of smileys that aren't in the Gathering of Tweakers smiley
set. So I added those smileys too, and made sure that as much as
possible there is a 1-on-1 mapping from GoT smiley to MSN smiley.
