[Tagging] Feature Proposal - RFC - (Traffic Signals)

[fly]

Additional to below I want to mention that on a micromapping style a
traffic_signal is placed one the pedistrian crossing or the stop_line. I
even came across ones one the stop_line and an addition highway=crossing
on the pedestrian crossing.

I am tagging direction=* for the direcion it faces.

Together with the :lanes tagging you do not need any relation at all but
could simply add the information on the node with :lanes tagging
