Simple Discord Link

• REQUIRES CraterLib - Modrinth
• Migration guide for V2 users

Bug Fixes:

• Reworked the linked commands permissions to that it actually respects role/user permissions
• Fixed an issue with the account linking commands adding duplicate entries
• Fixed an NPE error when a tellraw command has no player linked to it
• Fixed messages only being relayed when a player is vanished, with vanish installed

New Features:

• Added a channel filter config option to limit linked commands to certain channels
• Added a config option to allow changing how often the channel topic updates. Still limited to 5 minutes as the lowest
