META: Server changes

Overnight tonight we'll be switching to a new host for HeroMachine.com. Hopefully this will drastically increase speed and reliability for the entire site and all the apps. You shouldn't notice any change in saved characters or your account, but I wanted to give you a heads up just in case.

I'll update you when the changeover is finished. Thank you for your patience as I continue to try and make the site as easy to use as possible!
