2.8.5 - Critical fix and minor feature additions

This version fixes a critical issue in v2.8.4 that caused removing a single block in a merged region to either not work, or remove all of the protection blocks of that merged region.

Other Changes:

• Added /ps on|off (you will need to update messages.yml in order to get the new help message for /ps toggle|on|off)
• Only add id or name, not both to /ps home tab autocomplete
