Improve EOSdash.

Make EOSdash use UI components from MonsterUI to ease further development.

- Add a first menu with some dummy pages and the configuration page.
- Make the configuration scrollable.
- Add markdown component that uses markdown-it-py (same as used by
  the myth-parser for documentation generation).
- Add bokeh (https://docs.bokeh.org/) component for charts
- Added several prediction charts to demo
- Add a footer that displays connection status with EOS server
- Add logo and favicon

Update EOS server:

- Move error message generation to extra module
- Use redirect instead of proxy
