Added Twitter Feed

Composed a couple of tweets and added twitter widget to the social box.
Adjusted layout of boxes a bit too.
Styled club page

Club page now has a place for an avatar, and a bunch of other
information.

The club title is shown, with its abbreviated name next to it. Under
that is a scrollable box with the club description. To the right is all
the social links including twitter, facebook, and www website. There’s
also a join club button. The club rego id has been stuck in the top
right corner.

Lots and lots of nesting going on in the CSS, but it all works well.

Tested to work on FF, Safari, and Chrome
