Temporary Minor Mood Buff for when relatives of colonists come to visit

[TrapsterJ]

Just thought It'd make sense that there is an event notification for when a relative either passes through or is apart of a raid/caravan yet it doesn't really hold much significance besides if you wanted to kidnap them and make them apart of your own colony for family's sake, so why not give it more benefit? If you were trapped on an unknown world and suddenly your father or something appears then I'd like to believe it could benefit the mood slightly. Can work both ways as well, maybe they've got a bad relationship and can affect how positive it may be. I know that it's quite minor but it could work well as part of a larger mod/update that adds more variables for mood. Just something I thought of it that might already exist but oh well.
