Add configuration proxy for real time configuration tweaking

[kamikaz1k]

• use config proxy to fetch config values (so we can store overrides)
• add UI to expose all config values
  • for input values pressing enter commits the new value to the game (there is a console log for confirmation)
  • text and number/decimal is handled appropriately
• config debugger persists to localStorage (inspect via window.localStorage.__configOverrides) if you enabled persistence via debug flag: persist-config-debug
  • http://localhost:3000/?quick-start=false&persist-config-debug=true
