Prepare for Travis CI
Run the Rails server in the background for testing
Ignore build subfolder
Gems include Rake
Travis needs Rake at the top level

Removed XcodePages gem. Travis does not compile the documentation.
Clone the dependencies during "install"
Enclose script commands in double quotes if there's a colon
Concatenate the commands

Will Travis run them now?
Remove Rake gem dependency

Assume Rake appears somewhere in the sub-dependencies.
Remove before and after scripts

Travis launching a Linux worker. Not right.
Remove top-level Gemfile
Trash the Rails subproject

Does it help Travis? Travis CI seems confused about language and environment.
Test against Rails app on Heroku

App at http://active-resource-kit-tests.herokuapp.com/.
Do not launch a local Rails server in the background
Some Post titles and Comment texts ARE nil

Do not assert all non-nil.
Trailing slash ignores the folder

Including everything underneath it.
Merge branch 'hotfix/travis-ci'
