Previously the metamask controller only supported a single UI event listener, which wasn't useful for having a separate notification UI open at the same time.
Also reduced the notification's complexity down to a single method, which is heavily re-used.
Still has an outstanding bug where if the plugin ui dismisses the last tx, it does not close the notification popup.

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.
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.
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.
Calls to `eth.sign` are now transiently persisted in memory, and displayed in a chronological stack with pending transactions (which are still persisted to disk).
This allows the user a method to sign/cancel transactions even if they miss the Chrome notification.
Improved a lot of the view routing, to avoid cases where routes would show an empty account view, or transition to the accounts list when it shouldn't.
Broke the transaction approval view into a couple components so messages and transactions could have their own templates.
When starting up, we now create a `web3` inside the `background.js` process, which we pass to the `idStore` and ask for the current `network`.
We include the `network` on `app.metamask.network` in the state object.
We re-request the network when changing provider.
We filter the transaction list for transactions that match the current network.
Transactions are now stored, and are never deleted, they only have their status updated.
We can add deleting later if we'd like.
I've hacked on emitting the new unconfirmedTx key to the UI in the format it received before, I want Aaron's opinion on where I should actually do that.
