Object Command & Entity Spawn Changes (#492)

- Redid object paste command
    - Added rotate flag to paste with rotation
    - Added scale flag to paste with scale. Optional interpolation method can be used
    - Changes are now logged and can be reverted with the undo command
    - Fixed edit flag
    - Made the edit flag now update your wand even if it isn't in your hand
- Added object undo command
- Added object check command
- Added a surface target to spawn on for entities. This will fix mobs spawning in water
    - LAND for mobs that spawn on any land surface
    - ANIMAL for mobs that should only spawn on grass and dirt
    - WATER for mobs that should spawn in water
    - OVERWORLD for mobs that can spawn on both land and water (turtles, for example)
    - LAVA for mobs that can spawn on lava (striders, for example)
- Attempted to fix PAPI complaining about registering on the wrong thread
- Fixed console spam for entities (was due to the mount event being called async)
- Fixed grass paths and a few other update breaking blocks
    - Made it so if a block state changes on an update, it will now use as many as the other states as it can rather than not use anything
- Patch to stop people naming the world 'Iris'
