[amenity-symbols] Adding rendering for (major) waterfalls

In various parts of the world major waterfalls are conspicuous landscape features and tourist attractions. Mapnik fails to render these at all with the result that certain waterfalls have been 'tagged for the renderer': e.g., Iguazu and Rheinfalle.

It is suggested that waterfalls pretty much fall in the same class as cliffs and barriers and can be treated using the same rules. Furthermore the type of line symbolizer required for waterfalls is similar to that of cliffs (a line, with some ornamentation on the lower (downstream) side).

Light experimentation suggests that the following changes are required:

1. Create 2 new line symbols "wfall.png" and "wfall2.png". Example of latter attached.

2. Create a new style, along these lines (basically 'cliffs')

   <Style name="waterfalls"> ([waterway]='waterfall') 25000 100000 ([waterway]='waterfall') 25000 </Style>

3. Alter the layer 'line features' along the following lines

   cliffs waterfalls barriers mapnik true localhost mapnik 5432 (select way,barrier,"natural",man_made, waterway from planet_osm_line where barrier is not null or "natural" in ('hedge','cliff') or man_made='embankment' or (waterway='waterfall')) as roads postgis mapnik

I support the request for rendering waterfalls.
However, I would prefer a polygon for tagging, because many waterfalls are not vertical, but inclined and may descent on a longer way. So also rapids could included.

Did everyone completely forget this ticket? Waterfalls are still not rendered at all. Even shoving a simple stupid icon would be a progress.
