OrbisGuard Mixins

# OrbisGuard Mixins Patch v0.11.0
### This patch updates the mod for **Hytale 0.7.5**, adding a new flag: ***world-events***! Now this flag will be used for future events happening in the world. 

## What Changed
- Added the `world-events` region flag. It allows events by default; set it to `deny` to keep event sites out of a region. This works independently of `mob-spawning`.
- Denied event sites are skipped before their actions run, with cleanup limited to that event instance.
- Fixed NPC spawn denials so they fail safely without causing an error or starting flock setup.
- Improved event placement checks for rotated prefabs and trigger volumes, including when the TriggerVolumes module is unavailable.
