These external modules now have their own test coverage and build enforcement. This allowed me to somewhat more easily add good tests around our personalSign strategy (held now in [eth-sig-util](https://github.com/flyswatter/eth-sig-util), and allow each of the keyrings to import that, etc.
Provider egine bump
Remove presence of message manger in keyring controller
Change the status wording fom conf to approved
make Message manager a class
fix messages not being apart of the badge
re write message manger to better reflect controller pattern
Now any strategy for importing a private key that can be described as a pure function can be very easily turned into a MetaMask import strategy.
I've created a generic and reusable UI action called `importNewAccount(strategy, args)`.
The `strategy` is a unique identifier defined in `app/scripts/account-import-strategies`, and the `args` will be passed to the member of the `strategies` array whose key matches the strategy string.
Strategies return private key hex strings, and are used by the metamask-controller to create a new keyring, and select that new account, before calling back.
This also implements @frankiebee's idea of showing the imported account when it's been imported (my oversight!).
This commit only moves us to this architecture, keeping feature parity for private key import, but has some untested code for importing geth-style JSON files as well!
