Add a step to create a root route

We discovered that rails 4.0 on heroku would throw an exception going to the index page if you did not have a root route defined.
Add Missing Step

In the directions, we have "cd ~", followed by "cd railsbridge".  The students are getting directory not found.

This change adds a step after "cd ~" and before "cd railsbridge" to create that directory.
