Upgrade React to 16, plus upgrade related components

[dpgraham]

• Upgraded React to 16 and ANTD to 3
• react-router-redux is deprecated and react-router is outdated, so upgrade those both
• Had to do some heavy refactoring to get it to work like it did before. Used the latest https://github.com/electron-react-boilerplate/electron-react-boilerplate as my reference point
• Hot loading was broken before when porting to ParcelJS, now it works again. The router needed to be updated.
• CSS is broken now. That's why this PR is to have it merged into a separate branch called react-16 and we can break up the upgrade into separate PR's until it's ready to be merged to master.
