Warning: These are new features that might lead to bugs. Make sure it's working before placing it in a production server, in case my tests didn't catch some issue.
Changelog:
NEW feature - There is now the option to have players get tagged by ANY damage (lava, fire, etc). Obviously not the case for just PvP servers but some users have requested it.
NEW option to prevent NPCs from spawning inside a region with pvp deny. This option comes enabled by default now.
NEW option to disable area protection for players with PvP disabled.
Fixed compatibility with 1.7.10, NPCs should work again in that version.
Some internal changes in code related to dependencies like Vault and WorldGuard. Got the code looking a lot cleaner.
