Update to Chisel3

[chick]

@ccelio I'd like to update this document to Chisel3 it seems to be the most findable chisel style guide out there. I'd be happy to submit a PR to this repo or could fork to a chisel organization. Do you have any preference?

I’d be happy to accept a PR to update to chisel3; I think I tried and never finished myself. I’m also not offended if you want to fork now or later to have a more “official” url for the repo.
