after reading this thread (http://meepcraft.com/threads/ashop-command.60514/) i thought maybe, instead of spending the time to add a whole new command, we could tweak the existing /warp shop system.
i propose that, instead of having to type in "sell" or "buy" and then a number, they should merge it into one so you could do "sell 10" to sell 10 items or "buy 5". Regular old "sell" and "buy" could be repurposed for selling all that you have or buying all that you can afford/keep in your inv.
(maybe we could add a confirmation to "buy" to confirm the quantity and price so someone doesn't accidentally deplete their /bal)
