Offline availability about helpful-information HOT 3 OPEN

Possible future features:

• (big restructure/refactor) Build static version in HTML

  • • offline caching during visit by Service-Worker
  • prefetch of all other pages?

• (enhancement to add) Cache Sheets API responses by Service-Worker (as fallback)

  • with "possibly out of date"-warning

• (lower priority) Cache external images using Service-Worker, so they're only downloaded once.

Actually, after the refactoring of #200, everything works offline.

Visitors have to open a specific Region-page at least once.
After the visit all sheet-data is stored locally per region, so multiple regions can be stored for offline use. (Up to max 8 regions? Depends on use of Q&As. Can be configured differently.)
After 7 days the data is considered 'too old'; This can be configured differently too.

Images/icons are not all (pre-)loaded, so some 'holes' will show during offline use.
