Sorry apparently the gas fixes weren't in the last commit, but are in this one.
As reported in previous commit, fixes a bug where initial estimate is not derived from the network.
Also fixes a bug where clicking "reset" does not clear our custom validation warnings.
These were only separated originally so we could make the notification-based TX approval work, which provided its own buttons.
This two templates are logically highly coupled, and keeping them working while separate has been difficult at times, and has even required resorting to dubious practices, like using React's `refs` pattern.
This combines them into one fairly large component, but I think it's ok, we can still break this up into components, just not the separation that it had previously.
Also added a new state to try to make UI dev mode work again, but it has other issues, like #1128, that need to be addressed before UI dev mode can be used again.
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.
