Small improvements/Polish

Changes:

• The NW.js window now waits for Webpack/TS to finish spinning up before displaying in development.
  • Thanks @DieserMerlin (#3)
• Updated dependencies.
• Added a "Show DevTools" button (only visible during development).
• Clear out require and process. Still available under window.nw.
  • It was brought to my attention that Monaco Editor selfishly uses require, not unlike Angular itself selfishly using global. Pulled out process because, why not at this point.
• Updated test setup to better mock NW.js
• Cleaned up README.md.

Diff since last release:

• v1.0.0...v1.1.0
