Modified views for openstreetmap-carto-de.

Normally, osm-carto-de uses a hstore-only database, and emulates the things itself and openstreetmap-carto need with views on that.
We instead use the normal openstreetmap-carto-style (because it is faster and better maintained), and emulate what
osm-carto-de needs with views on that. These views have a _de appended to their name.
That means that we have to append a _de to all table-names in project.mml after
every update.
