Generates a macro that uses a random hearthstone from your toybox. Works better than writing your own macro since you don't have to figure out the toy ID for each stone, plus that ID can change when you get a new toy and if you have filters set in your toybox UI. Creates a macro named RHT upon first logon RHT to find it easier. After the first cast while not in combat, it is renamed to <space> and will not display lettering anymore. Additionally, it deletes the regular hearthstone to save you bag space. Should be no issues with localization since everything is based on item ID.
