Bukkit

• Added a routine to catch explosions and check for destruction of shops. It either cancel it, or delete the shop, depending on setting in config file.
• Config.yml support, with many of the properties turned into config options.
• Added configurable price per buy/sell showcase, in case someone wants to charge for creating a showcase. (user request)
• Added world blacklist (allows server operator to disallow SCS in some worlds)
• Fixed threading bug that resulted in server crashes at random times
• Text fixes and small bug fixes from previous commits.
• Created "safe" inventory functions, so that all items stack sizes and data values are respected, and the true amount of items given/taken is returned. (fixes stack size problems, data value problems - like dyes and colored wools)
• Made sure all routines use the safe inventory functions.
• Added: /scs limit to change the max amount a buy shop will buy.
• /scs remove will remove as much as the inventory as possible, and only remove the shop if all the inventory has been removed.
• Added currency formatting from the economy plugins.
• Added /scs last - displays information about the last transaction
• Added /scs undo - undoes the last transaction (if possible).
• Changed "shop" to "showcase" in messages. Helps differentiate a shop (which sells a collection of items), from a one item showcase that may be in a shop.
• Other small changes
