advance offline

let the user take pictures and upload them to the map even when offline. As soon as the app goes online the pictures will be sync with the server.

• the app should open when offline
• upload in background
• retry if error
• when offline: be able to geotag
• persist queue when the app closes
• need to upload the scheduled files when back online (app open)
• need to show progress
• cancel upload
• multi tabs concurrency (????)
• disable sign in button when offline
• write feedback
• enable upload button when starting the app offline
• QA

is it possible as PWA ? to investigate

@joykuotw what you think ? We'll need to investigate with Firebase offers anything out of the box. If not, I did some experiments with indexDB and it works pretty well...
