Overflow-y: scroll in body

Added "overflow-y: scroll" to stop page from shifting.
This adds a grayed out scroll-bar to pages that doesn't have one to stop the page from shifting ~10px when you switch between them (for instance between "Matches" and "Home"). 

Some people don't like the grayed out/low opacity scroll-bar to be there when there's no need for one, but I think its nice to have the pages not move when you navigate the site. Its up to you what ever you think its best, it was just something I noticed directly and thought it might be worth taking into consideration.
