Redid new version check, works better and gives changelog in game.
Added /em whatsnew command which lists the changes in newer versions.
Removed notifyOpsOfNewVersion option, created permission node "exchangemarket.loginNewVersion" instead.
Removed rounding of prices before inputting into DB.
Creating a sell order will first sell your items to buyers above your asking price. Same for buy orders except buying items from sellers below your asking price.
