[OSM-talk] New road style for the Default map style - real changes are now appearing

[Mateusz Konieczny]

Fortunately some changes make sense independently and it is not
necessary to submit them in one giant "let's change everything" PR.

At this moment there are three proposed changes extracted from
redesigning roads.

Comments and feedback is welcomed.

Start rendering of minor roads later -
https://github.com/gravitystorm/openstreetmap-carto/pull/1682 

Rework living street and pedestrian -
https://github.com/gravitystorm/openstreetmap-carto/pull/1684

Make railway=tram with service tags less visible -
https://github.com/gravitystorm/openstreetmap-carto/pull/1676

A two less related to roads, but also prepared as part of this project:

Move power areas closer to industrial areas -
https://github.com/gravitystorm/openstreetmap-carto/pull/1680

Show man_made=bridge -
https://github.com/gravitystorm/openstreetmap-carto/pull/1633
