Travelling Consumerist merchants + salvage nicks

High Chairman of Consumerists can spent 150 gold each year to create a "Broker"
Brokers travel to random courts, trading in luxuries, offering loans, and buying/selling Old World artifacts
Brokers are eunuchs, and skilled at intrigue... robbing/banishing/etc. will have consequences
A broker that amasses 500 gold returns to the High Chairman to retire
Nicknames from owning Old World items are now only acquired if you have certain traits
AI will not sell salvaged items to brokers if they have a nickname associated with that item
Also fixed a missing bracket in canada.txt and made a couple other minor tweaks
