RegionGuard

• Added weather flag that allows you to set the weather for a region.
• Added thunder flag that disables thunder/lightning in a region.
• Added __global__ region that affects the whole world. All flags are defaulted to off/allow.
• Added Beacon flag that allows you to give beacon effects for a region.
• Added passive-entity-damage flag. Untested.
• Fixed certain items being interactable when they shouldn't be.
• Updated tab prediction to include beacon effects and __global__ region.

Work in progress:

• Invincible, Teleport-Allow, Teleport-Deny flags.
• Some items are still not working properly inside block-place deny and block-break deny regions.
