Allow leading others along to a new space in a more automated way

[ClaudiaMia]

We want to add a more involved "invite along"/"lead along" system between spaces, but there are several technical steps that need to happen before that is a thing - right now you can't even search spaces from inside a space.

The idea for the future is this:

• You lead one or more characters inside the present space, as you would between rooms
• You open the in-space space search to select an existing space
• Or: You open the in-space space search to create new space
• You try to enter, but instead of that happening you get a dialog that you are waiting for confirmation from people that you are leading / that are following you
• You can cancel this anytime, or leave behind people that didn't confirm and go without them
• You see in real time who of whom is following accepted so far
• People that are following you get a prompt to confirm this switch, getting info about the new space inside it
• Switching spaces does not break the character follow

This has benefits of better integration, working well with multiple people following at the same time, directly ties to the existing follow system, and the flow doesn't differ much from switching spaces yourself. It is just technically a bit on the complex side.
