Mob Spawners

Fixed --amount argument in give command not actually doing anything
Fixed issue where mobs have a chance to spawn outside the radius if they attempt to spawn inside a block
Fixed issue where spawner mobs would not despawn overtime (time configurable with the spawnedMobDespawnTimeSeconds setting
Added the ability modify the max spawn amount in SpawnerSpawnEvent.Pre

NOTE

This will not modify the amount spawned it will only change the cap for spawned entities example, if you have the spawn amount set to 3-5 and modify the setMaxSpawnAmount value to 3 it will spawn a max of 3
