Added ability to have chests and signs in different worlds (AllowMultiWorldShops global setting in config, disabled by default)
Added ability to use raw xp instead of xp levels by using optional parameters (Check the PDF for takePlayerXP and givePlayerXP in the Blocks section for more info) (Thank you EssentialsTeam for your raw xp fix because Bukkit is silly)
Added new variable !hasxp to show the player's current xp in messages
Added new default sign [Command] to run commands listed on lines 2 and 3 of the sign
Added new variable !line#, where "#" is the line of the sign to be used in the "commands:" section of the config
Code refactoring for better hook implementation
Using SignShops that take or remove items from your inventory, with a written book in your inventory as well, will delete the contents of the book. There is no way for plugins to store the information written in books for 1.3.1 yet, so we cannot fix it until the Bukkit team updates their API.
Upgrading to SignShop 2.1+ from the SignShop 2 beta or SignShop 1? We recommend regenerating your config. If you don't do this, you may encounter problems with the Variable Amounts setting in the config, iSlot signs, and outdated error messages (among other problems).
