WorldProtect

Fixed Entity:
- Fixed Entity issue: old entities can no longer be picked up just by walking into them.

- Fixed flamethrower behavior: it no longer leaves black blocks behind when fire spread is disabled.

Fixed fire-spread detection:
- Torches are no longer treated as fire spreading.
- deco_fire is no longer treated as fire spreading.

Added two new region flags:
- grass-spread
- mushroom-spread

Improved grass and mushroom spread handling:
- Spread can now be properly controlled by region flags.
- Region priority is respected, so allow/deny works correctly between global and local regions.

Added the ability for admins to open the global region menu for their current world with:
- /rg menu __global__

Improved the mob-spawning flag:
- Reduced load caused by denied mob spawns.
- Reduced mob flickering when spawning is denied.
- Improved priority handling, so global deny and local allow work more correctly.

Added configurable claim commands:
- /claim
- /autoclaim
- You can now fully customize these commands in the config.
- You can also add custom aliases for the main /rg command in the config.

Added AutoClaim menu configuration:
- Each of the 6 sliders can now be enabled or disabled separately.
- Disabled sliders use fixed values from the config.
- Enabled sliders continue to work normally and do not affect disabled ones.

Added support for AutoClaim vertical max mode:
- up and down can now be fixed to maximum possible values based on the player position.
- This makes vertical claiming easier to configure for full-height regions.

Added separate permissions for:
- addmember
- removemember
- addowner
- removeowner
- /rg remove

Updated member/owner logic:
- Only region owners can add or remove members/owners in their own region.
- Members can only remove themselves, and only if they have permission.

- Improved global region convenience and region management behavior for admins.
