Advanced Fluid Handling still builds its Space Exploration valves, but the items they are mined into and placed from are no longer defined. With both mods active, loading stops with:

Error in assignID: item with name '80-overflow-space-valve' does not exist.
Source: 10-overflow-space-valve (valve).

The name in the message varies, because nineteen entities share three missing items: 80-overflow-space-valve, 80-top-up-space-valve and check-space-valve. This patch creates them.

Two smaller things come with it. Fluid handling buildings from every mod are collected onto the Advanced Fluid Handling tab instead of being split across two. And when Configurable Valves is installed, the Advanced Fluid Handling valves are hidden rather than offered alongside it, without removing the prototypes, so saves that already use them keep working.

Nothing else is touched, and the mod does nothing unless Advanced Fluid Handling is active.
