Make a nicer landing page

The landing page now has some boring text on it. I don't think people are going to read that and I actually think it would be better if it's not on there.

I'm not 100% sure what to replace it with yet. I think it would be nice to start with the text that we will soon end up printing on our business cards/mini flyers. Maybe we want some more information, and maybe we also want links to documentation pages (after !7 (merged))
