Add map of Nearby places needing photos (currently only have list)

[misaochan]

Some people would prefer using a map to a list, as @VojtechDostal and John Lubbock (Wikimedia UK) have suggested. A map would be easier to gamify in the future (a la Pokemon Go) if we wanted to as well.

Potential task for Vienna Hackathon 2017.

The Google Maps-based MapView is not available to devices without Google Play, so better use this OpenStreetMap-based replacement: https://github.com/osmdroid/osmdroid

Ah yes, good point. Also I suppose we need to consider how we want to switch between the two views, and which one to use as the default.

Can we use https://maps.wikimedia.org as a tile server?

[nicolas-raoul]

@tobias47n9e Unless we grow to millions of users overnight AND make the map the default activity, we can safely assume that they won't be bothered by our impact.

I was interested in contributing on this feature. Are we planning to pick it up at the pre-hackathon or hackathon events?

[misaochan]

We were planning to work on it during the pre-hackathon, but we have other potential tasks for that as well (e.g. making the switch to Wikidata). If you would like to work on it now, please feel free. If it's completed before the pre-hackathon, we can just work on the other potential tasks, or alternatively if it's partially completed, we can use your work as a base then.

This has been implemented and released in beta, please create an issue if anyone is having any problems with it.
