Site should have an about page

@mitchhentges When I did these changes I had forgotten to do them on a separate branch from master :S. When making pull requests please do them from a separate branch if you can.
@mitchhentges This, like a lot of the other content, was probably copied from the previous website where a lot of it originally came from the first board president. Our official mission statement on Facebook and Twitter is "We're here to provide a student voice to the Computing Science faculty and to help provide social and academic support for Computing Science students".
