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.
