Add info for Rails 5 / Sprockets 3

[jmarceli]

Hi, is this gem still required for Rails 5? I didn't find any info if it is possible to compile both assets versions in Rails 5 without this gem, so I assume it is still required. It would be nice to add some info to the README.md.

This fork has some Rails 5 fixes. No idea about complete compatibility but it's working how we use it

The changes in that fork are made by me, they are not to fix Rails 5 problems, they are just for some server setup problems.

Basic functionality seems fine to me in Rails 6, FWIW. What issues have other folks been seeing?

[dmolesUC]

OK, here's one: it looks like JS in public/packs/js doesn't get copied to the non-stupid path. Not a big deal for me as I'm only using this gem to statically link CSS and images in my 404.html and 500.html, but might be an issue for some.
