QuickStack

Allows users to use a command that identifies partial stacks of items in nearby chests and moves stacks from the player's inventory to those already in the chest, enabling quick storage. Here's a video demonstration:

Commands
/stack
Attempts to combine items from the caller's inventory with partial stacks in nearby chests.

/qsradius [number]
Adjusts the radius for which chests will be considered "close" for stacking in the above command. Usable by operators by default.

Installation
Place the QuickStack.jar in your plugins folder; it should load when the server is restarted. The plugin maintains a config file with a single entry to store the desired search radius between restarts, adjustable by command with qsradius.
