Rails Tutorial updated for Rails 4.0.1

I’ve just updated the Ruby on Rails Tutorial book for the newest Rails release, Rails 4.0.1. If you’re updating your sample_app to Rails 4.0.1, you’ll need to change rails to 4.0.1 and bcrypt-ruby to 3.1.2, as seen in the reference sample app Gemfile:

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.1'
gem 'bootstrap-sass', '2.3.2.0'
gem 'bcrypt-ruby', '3.1.2'
.
.
.

Then run

bundle install
bundle update
bundle install
rspec spec/

(I’m actually not sure if both calls to bundle install are necessary, but they can’t hurt.)

As far as I can tell, there are no changes between Rails 4.0.0 and 4.0.1 that affect the Rails Tutorial, but please let me know if you run into any issues.
