Exposed sprockets_environment from Jasmine::Headless

* Allows for manipulation of the Sprockets::Environment for
    things like adding/removing pre/postprocessors from spec_helper.rb
 * Also, fixed specs that were failing on files_list.rb when
    run standalone due to missing require in file_checker.rb
