Cleaned up the Regional subforums

FYI, we cleaned up the "Regional" subforums today. Long overdue!

Moved a few things around to put the busiest regions at the top (surprise: US, then Canada, then Europe...).

There were lots of crickets in most of the individual US regional sub-regions (by sub-regions I mean e.g. "Southwest", "Northwest" etc.), so we just moved everything together under a single "United States" region. That freed up a lot of real estate on the forum index, which was the main goal.

Just a heads up in case you're wondering where something went.

No threads or posts were harmed in the process. :D They're all still there.
