Some basic CSS added

Ok so you are probably wondering why the branch is called stylesheet2 instead of just 'stylesheet'... basically when I did the git pull origin master to sync the master repositories together I was still checking out the new-branch-name branch as opposed to the master so the sync wasn't working (ahh seems to obvious now!). Anyway I realised what I did and in trying to fix it I just ended up making a new branch called stylesheet2 so that I didn't get too confused... anyway a lesson learnt there!

I added some CSS but it is really basic so still doesn't look too great, but I added a background, changed the font a bit... I want to make it look better but have run out of time for today so this is as much as I have done for now. Will work on it again tomorrow.
