Allow players to join multiple FCs

[Kaliesto]

Don't forget 5 FC houses on one character, sounds nice.

Well I was thinking based on some good benefits from joining Multiple FCs:

1) FC chests, your main FC don't have what your looking for? Check with the other FC you're in.
2) Looking for another FC focused on different things than your main FC, join that.
3) Forming FC Alliances for various reasons

Just a few I can think of.

Downsides -

1) multiple FC channels would be hard to deal with
2) Potential Drama, and more drama with the ongoing housing issue connected with FCs

I'm sure there is more downsides.
