[Tagging] Proposed feature - Voting - electricity

[Lukas Richert]

As there were no further comments to the electricity proposal, I'd like 
to try another vote. I've gone into more detail on the tag transition 
and deprecation and changed the tagging to only be used for public 
amenities and buildings, which was the main concern.

Happy new year to everyone!
