Update generator to add ReactOnRails spec helper

[justin808]

• Generator adds line to spec/rails_helper.rb so that running specs will
  ensure assets are compiled.
• Added more diagnostics for server rendering.
• Calls to setTimeout and setInterval are not logged for server
  rendering unless env TRACE_REACT_ON_RAILS is set to YES.
• Other small changes to the generator including adding necessary npm
  scripts to allow React on Rails to build assets.
• npm modules updated for generator.
• Updated all npm dependencies to latest.
• Update to node 5.10.0 for CI
• Change babel-runtime to be a peer dependency.

I thought it was best practice to still use class syntax? I don't care much either way though, they both look good.

Linter requires this now. If no use of class stuff, then you have to change to SFC.

I just meant make these checks into two separate checks. So have the rails helper check separate from the spec helper check. It's fine as is thoughl
