One bed to sleep with all - Polycule Edition

"What do you mean my spiderweb polycule can't all automatically handle their bed assignments? Totally unplayable, uninstalling."
-- Paraphrased from an actual conversation.

This is a slight modification of Densevoid's "One bed to sleep with all" mod.

For a straightforward one-to-many harem situation, Densevoid's mod already does a great job. However, in a many-to-many "free love" style colony, it quickly gets overwhelmed.

This mod changes it to allow colonists who own a bed to also be allowed to be a guest in someone else's bed (toggleable per colonist if you enable the button in Mod Options), and changes the sleeping logic to first try to join a partner already asleep in bed where they are the current guest.

This allows it to handle complex relationship webs easily; you can simply assign every colonist as a master of their own bed and they'll manage things from there.

Ongoing Games:
Should be safe to add, safe to transition from the original mod, and I think it's safe to remove too.
You should still make a hard backup save before trying any of the above, just in case.

Other Mod Compatibility:
- Possibly incompatible with Big and Small Framework. One person reported it can mess up peoples' sizes, another reported it works fine. A third reported "it will not cause problem usually, but with furniture add-on it do have chance of resulting in an anomalous behavior, as add-on will restrict giant-sized pawns from using normal or small sized beds, though it do not 'always' cause problem."
- Incompatible with More Slavery Stuff. It was reported as "it broke the bed so that there was no option when you selected the bed." Another reported "do not appears to be causing serious problem but when slave is involved it can cause odd behavior."
- Incompatible with Multifloors/Verticality. It's been reported to override this mod's features, preventing people from joining partners in bed, to the point they'd rather sleep on the floor.
- Incompatible with Stay in bed. It was reported as "The owner of the bed chenged, but the pawn wouldnt go to the right bed"
- Soft-incompatible with 3+ person beds. They can both exist in the same game fine, but setting a 3+ person bed to Poly Mode will cause weirdness with the bed's assignments.
- Reported as working with StK Room Lovin'

In general, it should be the same as the original.
