Pro Guides section added

As the Street Fighter Tournament Guide and the Definitive Team Fotress 2 Trading Guide are both somewhat popular, I decided to add them to the topline navigation under a new section “PRO GUIDES.” Going forward, any less-than-serious strategy guides will probably be added to this section.

Or, you know, I might just forget all about it until I am one day forced to delete them due to obsolescence. That’s also acceptable.
