WorldProtect

New:
- Added region flag: falldamage (allow/deny) — disables fall damage inside a region.
- Added region flag: mobdamage (allow/deny) — disables damage dealt to players by hostile mobs/AI inside a region.
- Added per-flag permissions:
  - worldprotect.flag.pvp
  - worldprotect.flag.falldamage
  - worldprotect.flag.mobdamage
  - worldprotect.flag.notify
  - worldprotect.flag.greeting
  - worldprotect.flag.farewell

Improvements:
- Added /rg reload to reload config, regions database and caches without restarting the server.
- Improved PvP protection handling in PvP-deny regions to reduce client/server desync warning spam during fights.

Notes:
- Flags are set per region using: /rg flag <region> <flag> <value>
  Examples:
  - /rg flag spawn pvp deny
  - /rg flag spawn falldamage deny
  - /rg flag spawn mobdamage deny
- /rg reload requires: worldprotect.reload (or bypass/admin permissions, depending on your setup).

Improved the plugin data folder name:
- Old: dev.worldprotect_WorldProtect
- New: WorldProtect
