	Module for detecting weapon type
    Parameters:
		healing, [impactdelay|range|knockback] = medmelee
		impactdelay|range|knockback = melee
		healing, [reload|minspread|maxspread] = medgun
		reload|minspread|maxspread = gun
		
		healing = medtool (if medmelee and medgun failed.)
		repair = repairtool

	Others parameters:
    	forcereturn: force the function to return the value inputted ; e.g.: p.GetWeaponType({args={healing=30,impactdelay=30,repair=30,forcereturn="medtool"}})
    	else: happens if all conditions fail; by default "unknown"
