Update Elm Language Support for Elm 0.19

[sentience]

This umbrella issue will be used to track work towards necessary changes to support Elm 0.19 as these become clear.

TODO

• Support formatted, navigable build output based on the new JSON compiler output
• Restore “ignore warnings” build variation (Elm 0.19 no longer has warnings)
• Restore “run” build variation
• Remove elm-oracle type hinting feature (assuming elm-oracle will not be updated?)
• Update “View elm-package.json” command
• Update README with all changes

I'm anxiously awaiting this. Is there something I can help with to move this issue along? :D

@lsunsi Have you tried the beta version? See the README.md in this repo for instructions. Are there any specific features missing from the beta that you're waiting for?

@sentience I actually didn't see there was a beta! I got a little confused about the warning on Elm0.19 and totally overlooked it! Basics seems to be working great (: REPL seems to be still pointing to the old 'elm-repl' binary, but it's a minor.

Thanks for the quick help, friend!
