[Tagging] Feature Proposal - Voting - natural=rock cleanup

[Friedrich Volkmann]

http://wiki.openstreetmap.org/wiki/Proposed_features/natural%3Drock_cleanup

Voting starts. It's now only about a wiki cleanup, because the recent thread
"convert imported natural=rock areas to bare_rock" made me drop the part
concerning data cleanup.
