Allow admins to change users' names
updated waiver
Lots of little things

This just includes a bunch of tiny little changes I've been making to
get everything working on the new VM running on the ACM server.

Also some random changes in the app to adjust for the game. Things like
the waiver, random text changes, and new relic update.

  Lots of little things
  updated waiver
Add a couple smoke tests for GamesController#show
Add IndexController#root smoke test
Add a bunch of tests and stuff

Importantly, remove the calls to check_login from the before filters,
which should hopefully cut down on double renders.
Clean up ApplicationController

Some unused variables, some variables used once, etc. Good stuff.

I don't know what I was thinking with "redirect_to root_url and return"
