Show location type on place detail

Improving on #5

I'm sorry; I was working from an old commit of shareabouts where there was no `label` on the `location_type` yet. I'll admit I was a bit confused for a second there! I think I understand now.

Is this better? I wasn't quite sure what to do as a fallback if there's no `placeType` defined for the `location_type`, probably there's something better to do than just returning `'point'`.
