[Tagging] Feature Proposal - Voting - Port and terminals

[Malcolm Herring]

To be consistent with the IHO definitions, any use of the word "harbour" 
should be used for the area of sheltered water and not any land areas. 
Those land areas adjacent to the harbour water should be classified 
according to their function (terminal, wharf, etc.) Therefore the tag 
"landuse=harbour" on areas that do not include the water does not make 
sense.
