Replace separate .js data files with server-side JSON injection

- Remove need to maintain duplicate .js data files alongside JSON sources
- Load JSON data once at server startup and inject into templates
- Dev and production modes use the same data sources

Removes:
- server/scripts/data/{travelcities,regionalcities,stations}.js
- gulp compressJsData task for bundling data files

server/scripts/data/travelcities.js
