Can't drop item when in inventory with different drop key

This has been bugging me for a while. I have a different key-bind scheme and have the [tab] key set to drop. And when I want to drop an item when hovering over it in the inventory and pressing [tab] it doesn't work because it's not the original bind for it. You guys should probably make it so that it doesn't check for Q but for the drop key. Probably a quick fix, and would be much appreciated. 🙂
