Remove flutie import.

Flutie gem was yanked in 7c3c377 but the import remained
Fix broken links in README

Apply 80-character width limit on long lines.
Add staging config variables to Heroku

These two variables are necessary to make the staging environment use
staging configuration.
Upgrade Rails to 3.2.12

http://weblog.rubyonrails.org/2013/2/11/SEC-ANN-Rails-3-2-12-3-1-11-and-2-3-17-have-been-released/
Bump to 1.2.0
Add Flutie to Gemfile

* We use `body_class` and `page_title` view helpers in the application
  layout, which come from Flutie.
* We had previously removed Flutie because Flutie 1.x included lots of
  styles which have been superceded by Bourbon/Neat/Smash.
* Flutie 2.x is just the view helpers and we think `body_class` and
  `page_title` are valuable.
Fix ActiveRecord attributes' blacklist

Suspenders previously added the line
`config.active_record.whitelist_attributes = false` but did not remove
the line `config.active_record.whitelist_attributes = true` later on in
the file, which reversed the line Suspenders created.
Add better_errors and binding_of_caller gems
Remove Spork and Guard

Use Zeus, Commands, or Spring instead:

https://github.com/burke/zeus
https://github.com/rails/commands
https://github.com/jonleighton/spring

They are superior to Spork for the following reasons:

* You don't have to commit anything into your Gemfile, spec/spec_helper,
  or version control.
* They improve the Rails bootup speed of rails server, runner, generate,
  console, and rake tasks... not just tests.
Update staging and production email delivery

* Use recipient_interceptor gem.
* Use the Mail gem's interceptor feature.
* Separate SMTP from intercepting responsibilities.
* Set up SMTP for production and staging.

Support Ruby 1.9.3 and 2.0
Bump to 1.2.1
Include factory_girl_rails in development env

Including FactoryGirl in the development environment ensures that
factories get created when default generators are used. Adding
FactoryGirl to development also provides factory functionality when in
the development console.
Fix SyntaxError caused by missing newline

Occured in staging and production environments

The error:

    /app/config/environments/staging.rb:1: syntax error, unexpected
    tIDENTIFIER, expecting $end
    ...ENV['EMAIL_RECIPIENTS'])require Rails.root.join('config/init..
Bump to 1.2.2

Patch version incremented for bug fix.
Remove Psych from Gemfile

The reason this was here was to resolve Bundler / Psych double loads

    `<class:Parser>': superclass mismatch for class Mark (TypeError)

https://github.com/carlhuda/bundler/issues/2068

The issue has been fixed in Rubygems >= 2.0 and Bundler >= 1.3.0, which
we should all be using now.
Switch web server from Thin to Unicorn

As the Rails application scales to more Heroku dynos, a lack of
concurrency can result in [poor performance](1) and an over-provisioning
of resources. Modifying the app to handle requests more efficiently is
a simple process with immediate benefits.

Unicorn is a [concurrent web server](2) that spawns several processes
within a single dyno without requiring concurrency or threading
awareness in your app.  Applications that migrate to Unicorn often
require fewer dynos and see increased performance.

The [config/unicorn.rb file](3) specifies the number of concurrent web
processes to run on each dyno as well as the proper forking and
termination behavior.

* Use semantic versioning on minor versions of dependencies.
* Upgrade dependencies.
Set up database before setting up RSpec

Fixes https://github.com/thoughtbot/suspenders/issues/169
Add Delayed::Job

* Use style-guide-appropriate database migration.
* Configure RSpec request specs to run jobs immediately.
* Run `Delayed::Job` workers via the `Procfile`.
* Ensure delay_jobs is reset when example fails.
