Cities and Houses are now able to transfer credits as BOUND.

This is an option, and not required, meaning that you can
still transfer credits as normal/unbound credits if you wish.

Optionally, you can transfer credits as bound, so that your
ever-loyal members won't be tempted to resell those cheapie
city/house credits on the open market.

HOUSE CREDITS TRANSFER [BOUND] <credits> TO <person> <reason>
CITY CREDITS TRANSFER [BOUND] <credits> TO <person> <reason>

Either put the BOUND in, or leave it out.

This is yet another improvement inspired by the carefully-
thought-out and well-proposed ideas submitted by Achaean
adventurers just like yourselves - only better!
