title: Regenerate dummy app
body: <p>Okay, somewhat into developing a plugin (first time), decided to install rspec, and in my haste deleted the test directory that contains the 'dummy' rails application.</p>
  
  <p>Nothing important in the dummy, but how do I re-generate it? It's truly gone, didn't commit it and the trash can is empty.</p>
  
  <pre><code>starkers@ubuntu:~/rails4/my_plugin/spec$ rails new dummy --skip-unit-test
  
  Can't initialize a new Rails application within the directory of another, please change to a non-Rails directory first.
  </code></pre>
