This PR adds a layer for `highway=motorway_junction` features. This implementation of highway exits in the transportation_name layer add to the existing layer table structure, and renames the internal column name from "construction" (which was already overloaded with non-construction usages) to "subclass", which will be less confusing to future developers. The string 'junction' is used as the universal sub-class for highway exits. A new documentation PR has been opened at openmaptiles/www.openmaptiles.org#69 to reflect these changes in the documentation.

This is the layer for labelling the highways. Only highways that are named `name=*` and are long enough
|
|
to place text upon appear. The OSM roads are stitched together if they contain the same name
|
|
to have better label placement than having many small linestrings.
|
|
For motorways you should use the `ref` field to label them while for other roads you should use `name`.
