Better package ordering

[curryducker]

• Added a key (@s) to package addresses which will be substituted for the ordering player's name.
• Added a config specifying if the key should be substituted. (default is true)
• Allow @s to be used in Package Port addresses

This allows for shops to send packages directly to peoples homes instead of a front desk. Just set the address to @s (or something containing it, depending on the way you decide to specify your home address) when configuring a table cloth. When ordering at the cloth, the key will be substituted by the name of the player that hands the shopping list to the shopkeeper. You can also use @s when configuring a redstone requester to make it use the name of the player that's configuring it.
