Fix copy key failing when player has no backpack

Browse Source 
Related to #1567, so I made this a function so it can be reused. People
should call this whenever they are adding a toolbelt item which the
player may already have. It has localized strings and handles spawning
the weapon holder on water, land and rooftop.

Tested both the sledgehammer and key copying. Confirmed all three
conditions are working.

/*
Description:
Checks whether the player already has the tool on their toolbelt and then adds it. Useful for batch crafting tools.
1. If they don't then it adds it to their toolbelt.
2. If they do then it adds it to their backpack. If their backpack is full it simply falls on the ground.
3. If they have no backpack it spawns on the floor as a last resort.
The player is given an appropriate systemChat message in case 2 or 3.
Parameter:
_this: string - toolbelt item classname to check and add
Returns:
false if item is not a duplicate, otherwise true
How to use:
"ItemSledge" call player_addDuplicateTool;
