Upgrade to Rails 3.2.16
Upgrade mongoid to 3.1.6
Upgrade bootstrap-sass to 3.1.0.2
Upgrade unicorn to 4.8.2
Upgrade faraday-http-cache to 0.4.0
Upgrade devise to 3.2.2
Update installation instructions in README

The part about configuring the admin app to point to the local API was referring to the wrong app. OHANA_API_ENDPOINT is defined in the admin app, not in the API app.
Go back to bootstrap-sass 2.3

Upgrading to Bootstrap 3 is more involved than I thought. Will do that later.
Upgrade newrelic_rpm (3.7.2.192)
