* Add better support for 3d buildings Change key from "levels" to "building:levels" as the "levels" key is non-standard and sees much less use than "building:levels" * Fix typo in sql definition and missing render_min_height * Add render_height and min_height to building.yaml * Simplify the render, switch numeric to int. Assume min_height cannot be negative. There are a few examples in overpass, but can't show below ground anyways in mapbox (https://github.com/mapbox/mapbox-gl-js/issues/3456). Also don't attempt to fix min_height>height * Remove colour as it is not currently used

All [OSM Buildings](http://wiki.openstreetmap.org/wiki/Buildings). All building tags are imported ([`building=*`](http://wiki.openstreetmap.org/wiki/Key:building)). The buildings are not yet ready for 3D rendering support and any help to improve

this is welcomed.
