[Tagging] Proposal for some additional power line tags

[Ole Nielsen]

Please see http://wiki.openstreetmap.org/wiki/Talk:Tag:power%3Dtower for 
some additional tags for advanced tagging of transmission towers.

I intend to add these tags to the 
http://wiki.openstreetmap.org/wiki/Tag:power%3Dtower feature page but 
first I would like to receive any comments you may have to these 
proposed tags. Please add any comments on the discussion page.
