Station Transponder

Station Transponder creates a new spacestation (artificial planet) under your control. This is vanilla mechanic (see https://starbounder.org/Space_Station for how it works in unmodded Starbound).

Structure
Unlike the BYOS ship, your station consists of predefined "modules" (such as Large Core, Mech Bay, Solar Array Hall, Greenhouse, Habitation Hall, etc.), which you can add to the station at any time. Exterior of the station is permanently tile-protected, so there is no risk of hull breach or lack of oxygen. Inside the station you can build normally.

Station starts with an indestructible Ship Teleporter and a control panel for increasing/decreasing gravity. It also has a Shiplocker (storage). Its starting module is a Small Core, which has an Airlock to the west (exit to space) and can be expanded to the north, east and south.

Beware that already added modules can't be removed/changed. If you place a Large Core somewhere, you can't replace it with a Small Core later.

Solar power and water

 * Spacestations don't have day/night cycle, so Solar Panel (and its upgrades) will produce the same amount of Power around the clock.
 * Water Generator and Liquid Collector won't work on spacestations. However, Atmospheric Condenser will.
 * Bees work on spacestations (all species). They will have normal production (no bonus/penalty for biome).
