[Tilesathome] The non-rendering of glaciers

[Ed Loach]

> Could someone apply this please?

Should captionless-z12 and osm-map-features-z6 also contain

+		<rule e="way" k="natural" v="glacier">
+		   <line class='natural-glacier'/> 
+		</rule>

like all the other files you're patching?

I don't know which files are used by what; I didn't think the osmAtHome one was used for example, but may well be wrong. I'd assumed that all the stylesheets were kept together in the stylesheets folder.
