Integrate with MyCrypto

[bmann]

Proof of Concept integration with MyCrypto, with status messaging in UX, and user-side translation section. Those are probably two separate areas that would be handled separately.

Getting started on this with a locally run copy should enable us to get to a PR / show it as a demo that other people can run as well.

@jenncoop can you put this on your list to review and see about writing up a better spec?

This is something that EITHER could be really great for us to just get done, or use this as an opportunity to bounty if we can write a good spec.
