Rails 3 incompatibility when symlinking non-digested assets

[etripier]

Hey guys,

Thanks so much for the hard work on this gem. It makes my work much easier and it's been a breeze to set up, even on the venerable Rails 3 distribution.

I'm seeing an incompatibility when trying to symlink_non_digested_assets in assets_precompile.rb. Broadly, the method attempts to read a list of file names from one of either the "manifest-*.json" or ".sprockets-manifest-*.json" produced by Sprockets. In Rails 3 (and the associated Sprockets version), those manifest files are actually YAML files instead of JSON.

I'd be open to digging and trying to patch the method to read the relevant .yml manifest file, but I wanted to see if you've considered that/have any interest. This is one of the only real incompatibilities I've found in getting Webpack up and running on Rails 3.

Thanks again!

@etripier We sort of don't want to maintain Rails 3 support with Rails 5 support. That being said, if you've got a simple PR that would make this work, please submit it!

We'll have #566 merged shortly.
