Title: Add therubyracer gem commented in default Gemfile

This add therubyracer to default Gemfile but commented since we want avoid the detection of existing JS runtimes on the system. (See #3619)

Also I plan to update Getting Started guide to tell new Rails users that they can uncomment this line when they don't have a JS runtime in their system.
