"/send" sends an item to a player from your invi

CMDBOOK-2154 - Reported by Melonking

Simple enough command, /send , sends an item from your imvi to another player, does not if their invi is full.

Start by locating the command registration and inventory-related entry points for the proposed `/send ` command. Check how existing commands identify players and remove items, then verify the behavior when the recipient's inventory is full. Done means the command transfers the requested item only when the recipient can accept it.
