Add a popup template to showcase OpenStreetMap data

[yohanboniface]

It's a popup template that know how to display data coming from OpenStreetMap. At this stage, it's very basic and only display contact informations, but I'd like to push such a minimalist version and see how users use it before putting more energy on it.

What's not done and may be in further steps:

• display a i18n label (bakery, swimming pool)
• automatically display an icon if none is set on the layer
• show opening hours, or at least show if the shop/amenity is open
• show more specific tags like the cuisine for a restaurant, the organic tag, etc.
• connect to panoramax/mapilary to have a picture…

There is no intention to cover all and every possible case, but only to focus on the main tags (shop/amenity…).

I don't get where OSM proprs are actually fetched?

props are just the normal feature properties. This template is supposed to be used when the features comes from OSM, either by an import or a remote URL (eg. overpass).
