[Tagging] Sidewalks vs Footways

[Serge Wroclawski]

There's an abandoned tag for sidewalks along the side of the road that
apparently has some use in the UK:

And there's a nearly identical tag proposal called Sidewalk:

I'd like to suggest collapsing these two tags into a unified tag and
making a final vote, and then fixing tags as necessary.

Thoughts?
