Re-added Adam's approach to instantiating webdriver in userland from homeland with the correct shared context fueled by a yaml file
Added the selenium standalone server and a stub for us to add a background execution of it. This is controlled in the yaml file with local_server true/false. Also amended the generator so it will put files in the test directory and append the proper file pattern of _beaker.rb. And fixed the shared_context so it looks in the test directory for the proper file pattern (removing this from the .rspec file in userland).
