Bukkit

Added '/scs unit' (defaults to 64).  This allows player to shift right-click (or sneak right-click) to buy/sell in that quantity.  Changing the unit only lasts while the player is logged in, and then reverts to the default.
There are some other small bug fixes as well.

Big Thanks to sorklin!
