Move to react, first round

[slipo]

Here's the first round of migrating to (P)React. This turned out to be a lot of work and I want to get this out for review and start doing smaller PRs.

Some things this gives us:

• Almost all features that are working already in master
• Preact (Migrate to React #9)
• A foundation in React to work with for the next release. We have a bunch of tasks and this provides something for multiple people to build on.
• Uses neon-js 2.2.1 from CoZ repo (Use CoZ official repo for neon-js #6)
• babel formating rules
• Redux for storing state
• preact-material-components as requested by @deanpress

Things to improve:

• Styling. It wasn't straightforward to map the styling over from the old way. I'm hoping @deanpress will take a pass at bringing his previous work over.
• Perhaps restructure the directories/files a bit
• Messages bring the popup up, but it doesn't show the authorize dialog yet. I think we should consider changing this dialog anyways because it should say where your coins are going and how much
• Send Invoke forms are hooked up but we need to integrate into neon-js to make it actually do something. Before we used a branch for this + Test Invoke. I figured out Test Invoke but we still need to figure out how to do the send preferably without forking neon-js.
• Import/Create/Export wallet and Config weren't working for me in master and still don't work.
• I'd like to improve the popup remembering things in between closing/opening, especially which route you were on and form values.
