Planet-unique data is incorrectly cached

[skiwi2]

Data that is unique for every planet (Defences, Fleet, Shipyard, Buildings, etc.) is currently cached per player via executeIfNotCached which uses getFullCacheKey, which in turn uses getSetting which uses getFullSettingsKey which uses the server group, universe id, player id and the key.

This means that if two planets have the same data, they will not get updated correctly.

As solution the planetId should be included in the cache key, additionally a new mechanism should be used to delete all cached settings when changing the OGNext instance URL.
