Name all our modules.
Move RailsServer spec helper class methods to instance methods, in preparation for pulling it out into its own gem.
Finish refactoring the interface to RailsServer to make it independent from Fortitude's particular specs.
Modularize directory paths better.
Factor out start_rails_server!.
Factor our some additional options into methods.
Small refactoring of some Rails support.
Hooray! Now we automatically handle the "--local" on "bundle install", so no more need to set an environment variable just to make specs go fast.
