Setup Active Admin

Ok. This is good. Setting up devise with active admin via [Rails for Charity](http://railsforcharity.org/blog/setting-up-active-admin-with-existing-user-model.html) didn't make any sense to me as far as setting the ENV variable. @boontdustie was instructing me to set it as I started my server, but it wasn't helping for when I needed to sign in without having that set from the get go.
