WorldGuard support for WDLCompanion

GitHub releases page

• Basic region support
• Partial polygonal region support
• Handle different ownership types

• It's possible (though I haven't fully investigated it) that some regions may be missed if they were not initially loaded. I don't think this will cause trouble since normally a player will be near the region they need, but it may cause issues. Or it might be that regions are already loaded and this is a non-issue.
• Polygonal regions may not be handled precisely
• Chunk overrides are not updated when regions are, since WorldGuard does not create any events for that. Players will need to manually refresh their permissions for changes to take effect.
