Not all pistes are in the database

[zerebubuth]

Because piste:type isn't listed in osm2pgsql.style, a feature which just has "piste" tags on it won't be considered "interesting". This happens quite a lot with interconnecting bits of piste, where they don't have a name that would make them "interesting".

It's a simple one-line fix to add piste:type as an "interesting" tag, but this would require a full database reload, which is a lot of time and effort. So this is just here as a placeholder - perhaps if we collect several of these kinds of issues it'll sum up to being worth doing.
