invite

Syntax: invite \<character\>
Syntax: invite temp \<character\>

'Invite' allows a player to enter your room even when it is not visitable.

If 'invite' has no arguments it will show people in your list with that flag
set.

If the first argument is 'temp' the flag will only last until you log out.

This command is a toggle.
