Requires coffee_script but coffee-script is not a dependency

With coffee-script missing from the Gemfile:

Yea that's because coffee-script is being required:
https://github.com/spree/spree_gateway/blob/master/lib/spree_gateway.rb#L3

It should probably be moved to a runtime dependency instead of development or only required if it's bundled.

I encountered this issue today with Ruby2.3.0 and the following gems.

source 'https://rubygems.org'
gem 'rails', '>4.2.6'
gem 'therubyracer', platforms: :ruby
gem 'spree', '> 3.1.0'
gem 'spree_auth_devise', '> 3.1.0'
gem 'spree_gateway', '> 3.1.0'

I added the following to my gemfile just before spree (note that sass load failure had followed coffee load failure).

gem 'coffee-rails'
gem 'sass-rails'
