U of A Official Colors and Logo

The only changes are to the .css files.  The red color was changed to the official U of A red.  Additionally, the page title has been changed to use the official U of A logo, rather than just a plain text 'A'.

I am a noob when it comes to web design, and am unsure as to the decency of the changes I made.  They looked good in the situations I observed, but I know that doesn't mean anything.

Additionally, I noticed there was a mobile.css, which I am pretty unsure of what it is doing.  Since I had no way of building the site to view from a mobile device, I figured I would submit for consideration the changes I have made, and we could go from here, rather than me just push the changes up.
