Change Sponsors Tab from Picture to Table

The current Sponsor tab is a screen shot from the website, and it shows. Either come up with a better picture, or add the sponsor information into a table. Parsing sponsor information from the website would be better, but static content will likely work for now.

There is JSON for Sponsor info available at http://2013.texaslinuxfest.org/sponsors_mobile?JSON_CALLBACK=sponsors
