New:
- Added a new module: **Force auto-kill**
- Using this module, you can now set all newly-placed spawners (**not pre-existing ones**) use auto-kill by default & players won't be able to turn auto-kill off.

Bugfixes:
- Fixed a minor bug which sometimes spammed errors into the console.
- Fixed "hologram has been toggled" message showing when placing the spawner, now the hologram will be created silently.
