There is no point in setting inTraderCity = "Any"; since you can use the
isInTraderCity variable to check if a player is in any trader city. Also
"Any" will return false for isNil, so the only time "Unknown Trader
City" was being used was when the player had not entered any city yet.
If they left a known trader and went to an unknown one the RPT message
would say "bought x at Any". Now it will correctly say "Unknown Trader"
anytime a purchase is made without inTraderCity being set.
Optimizes the code for the buyitems item listing (What was I thinking!)
Adds item count to buy/sell list (Useful for checking against
backpack/vehicle storage space constraints when buying multiple items)
Small logging fix.
* Advanced trading fixes/modifcations
This adds combine currency option to the Advanced trading screen since
@Airwaves man noticed it didn't have a way of doing it.
Updated stringtables with correct "paid" spelling and differing text for
buying/selling.
This also addds proper currency checking/reporting for the log system
that has been introduced, it's untidy but it works, instead of getting
"user bought x for 1000 currency" in a non coins server, it will convert
it to the proper 1 brief 5 10oz gold etc system (uses a new function
z_calcDefaultCurrencyNoImg)
This also adds a check to see if the buy list is empty (as per the
selling list) and returns text to the user informing them.
Re-arranged buy and sell so buy is on top of sell, it's a bit easier to
read then.
* Advanced trading logging change
This was missing from my previous commit, this changes the
server_tradeobject to check if it's being passed a number (single
currency) or text (my logging currency changes)
* Advanced trading rework
Fixes all problems @ebaydayz
