Minor update.
Fixed: no equipment dock

The universe lacked any equipment dock, required to change spacecraft modules, due to a bug introduced during the module overhaul.
- New ship module: Ship Equipment.
- Stations/colonies with both Shipyard and Ship Equipment modules now allow ship modification for docked ships.
- The Trade Station station class now has a default Ship Equipment module.
- The Ship Equipment module is now added to the build order of colonies with more than 1000 inhabitants."
Fixed: civilized worlds were mostly covered in ruins


A bug in wilderness removal and build-order simulation was creating excessive ruins. This also broke build orders and starting colony generation, as ruins filled all available land.\nAs a result, colonies became very poor sources and destinations for trade.
