Updated for Spigot/CraftBukkit 1.13. NOTE: Due to the extensive API changes in 1.13, this version of Armor Stand Tools is compatible with Spigot/CraftBukkit 1.13 ONLY. If you are running Spigot/CraftBukkit 1.8 through 1.12 then you can continue to use Armor Stand Tools v2.4.3.
Added the option of using a %player% placeholder when assigning commands to armor stands. %player% gets replaced with the executing player's name at time of execution.
Changed default armor stand equipment in config.yml to AIR so that by default new armor stands have no equipment.
