Parse map models and validate them (#13)

The enhancements:
- Added map validation that checks for some common errors that maps have
- /take: Does map validation but will still take the map even if there are problems
- /take: Improved the help text and added links to the maptest places
- /submit: Does map validation and will not let you submit if there are problems
- /submissions: Now shows the map's display name and creator
- Added an ESLint config and tidied some things up
- Updated some of the packages
