The 3 cells have been updated!

The changes are mainly about improving the experience-powered furniture scripts and some cleanup on the preset menu.

• Added furniture variants with built-in tie-down points that use the same reachability configuration as the main furniture.
• The experience system will now attempt to re-seat users that logged off while sitting on a piece of furniture.
• There is a new configuration option that allows to “reserve” a piece of furniture if someone logs out while sitting on it.
• I did some cleanup on the prison/narrow cell preset menu to make it a bit clearer to navigate (I also added a demo flag but that’s just for me really).
