Replace config-manager-singleton with one that is instantiated within the `background-controller`, and takes its persistence callbacks from its instantiated options.
Replaced class getters with more familiar get___() functions.
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.
Scrolling to the bottom of the accounts page now reveals a downward-facing chevron button.
Pressing this button shows loading indication, adds a new account to the identity vault, displays it in the list, and scrolls the list to the bottom of the page.
Any number of accounts can be generated in this way, and the UX feels intuitive without having to overly explain how HD paths work.
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.
No longer do our `mainnet` and `testnet` buttons set specific RPC urls. Now they set `provider.type`, which gets interpreted with code.
Currently the provider types of `mainnet` and `testnet` point to our new scalable backends, but these could be re-interpreted to use any other provider, be it etherscan, peer to peer, or otherwise.
Makes it easier for us to upgrade our infrastructure without incorporating migration logic into the program.
