This is a small, straightforward patch that I'd love to see merged:

[https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/4358-patch-add-root-option-to-activemodel-json-serialization](https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/4358-patch-add-root-option-to-activemodel-json-serialization)

It's all pretty self-explanatory, it basically just ports a useful option from to\_xml to to\_json, making their interfaces more compatible with each other. Feedback would be greatly appreciated.

Thanks, James
