eth-lightwallet was previously not salting vault passwords, potentially making it easier to crack them once obtained.
This branch incorporates the API changes to allow us to take advantage of the new salting logic.
This is still throwing deprecation warnings, but that's actually a bug in eth-lightwallet I wrote, [I've submitted a PR for that here](https://github.com/ConsenSys/eth-lightwallet/pull/116).
Fixes#555
* Add mozilla plugin key to manifest
* Move all chrome references into platform-checking module
Addresses #453
* Add chrome global back to linter blacklist
* Add tests
Signing now always takes a 64 digit hex string, and returns a message signature which appropriately pads r, s, and v with zeroes.
Need to verify with Denis that this is the behavior he requires.
Fixes#197
Also as a side effect, by creating this `iconFactory.cache` object, we have a convenient place for specifying stock icons for known contracts!
We can just hard-code image addresses in the `ui/lib/icon-factory.js` cache instantiation, and those values will be injected into the identicon image tag `src` attributes.
Fixes#122
Had used multiple actions for some transitions, which would lead to brief intermediary states.
Now making a few actions much more explicit about what they route to, so there is less intermediary logic, and we can transition confidently to the correct view.
