uninitialized constant Listen::Turnstile

[jmera]

To reproduce the problem (Mac OS X):

$ git clone https://github.com/joost/phony_rails
$ cd phony_rails
$ bundle install
$ bundle exec guard

Produces the following error (even after bundle update):

/Users/mera/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/guard-1.2.3/lib/guard.rb:48:in `setup': uninitialized constant Listen::Turnstile (NameError)

This was due to a change in Guard's listen dependency. Fixed in #70. 🍻
