JS runtime: "upgrade" to mini_racer

[ridem]

Why not upgrade the ExecJS runtime to mini_racer? I use it on my react-rails projects and it's making server rendering much more efficient.
react_on_rails have themselves moved to using it instead of therubyracer. Plus it fixed my setTimeout polyfill console errors that were coming from babel-polyfill.

If you read the first link, you may also be tempted to try sassc-rails. If you have gems that depend on sass-rails, here's a way to add it:

Hi @ridem. We use mini_racer in 2 projects and we want to be sure that it works correctly in all cases.
react-rails 1.10.0 polyfills setTimeout.
