Update the house sharing function

[SXTC]

There is a vast housing shortage and while you can share your private house with others, people are reluctant to give too much access in the fears that they'd lose furniture when the sharing stops... or someone taking off with them...

So my suggestion is to:

- Raise the amount of people you can share a house with to 5.
- When you stop sharing a house, the items you placed into the house are sent to you so you don't lose them.
- While 'decorating' people you share the house with can put stuff in storage, they cannot put it in their inventory unless its their own item.
- Add an option so you can choose how many item slots each person may use "or" auto share the amount of item slots with the amount of people using the house.
(so if the max slot is 300 and you share with 5 people (so 6 counting yourself) then everyone would get 50 item slots).

All that is left is communicate on who does what part of the house in terms of decorations. That way a certain form of peace of mind can be established knowing you had a part in the decorations without any of the risks.
