Send more items per trade

When trading within friends and corps, it is very tedious to only be able to send 3 items at a time through the mail. To send large quantities you must post it to the “trade” market and risk someone else grabbing the offer before your target does. I suggest the ability to send “stacks” of items through the mail to specific players, but require the target to receive the package within like 30 seconds of sending to prevent abuse.
