Bukkit

This works in the latest bukkit DEV build for 1.1

• Added a new transaction engine
  • When purchasing or selling, price will change by velocity for each item sold or bought.
  • IE, if you call /buy stone 5, the first stone will be purchased for the current price, then the second will be purchased at (price + velocity), and then the third will be (price + (2 * velocity)) and so on.
  • Selling works the same way, except you subtract the velocity.
  • This new system eliminates abuse thus far (I haven't been able to abuse it while testing).

• In order to suit the new transaction engine, the price command is modified
  • /price [Item] [TypeOfTransaction] (Amount)
  • An example is /price stone sell 5
  • This will retrieve the current price of stone, the description, and the amount you will earn from selling 5.
  • The buy command works exactly the same, but returns the cost of buying the amount
  • If the amount argument is left out, it will use the config.yml default value.

• Changed to use Vault for permissions
  • Hopefully this will fix some issues some of you had with perms.
