[Tagging] complete tagging of all 'right of way'-cases FOLLOWUP

Hey guys,

If the first one was TL;DR ... I start with working on this proposal to
implement a give_way as a relation. This might be one of many to this
topic and I'll follow up every different one when I start working on

I thought some hours about this old proposal[1] and decided to
update[2] it.

It now includes the ability to tag the 
* used sign (directly at the intersection)
* road markings, like a curb or a dotted or solid line
* main operational function of this intersection, like a traffic light.

The last one is necessary because we got intersection with stop and
yield signs here, which are located at the traffic lights. So if the
traffic lights are off (in the night or just non-operational) the signs
located at the traffic lights are applied.

When the traffic lights are shut of every night, we can add that
information to the node at the via tag, to disable the traffic light
tag in those time periods for the routers. Then the give_way- or
stop-relations come into action.

It now also includes lists of cases where it should be used and cases
where it shouldn't. Explicitly changing the recommendation to NOT use
it on roundabout & removing the example for it).

It's also recommending the simple solutions for a priority-to-the-right
(not yet written) and the all-way_stop.

If the mapper wants to map more details, like the curbs, signs,
hour_on/off or the class of vehicles where this applies, we have to go
the relation way and create up to 4 relations to one intersection - I
just don't see a simpler way with the same flexibility.

As always: Feel free to fix logic and language issues in the proposal -
I'm not a native speaker, there might be many.

I hope for more feedback on this from you, guys.

Best regards
