Fix wither explosions breaking protected blocks

[T14D3]

Prevent wither explosions from breaking locked blocks (Also bumps PlaceholderAPI version because plugin won't compile otherwise)

#320 already bumped the PAPI version. I will look at this more in detail later.

Apologies, forked before that pr was merged.

Isn't it weird that EntityExplodeEvent doesn't cover Wither explosions? That catches Creeper explosions for example... Though maybe just for being cautious this change is good to cover maybe some unknown cases. Idk how often this event is called, but given it's just a generic "change" event I would assume that it get's triggered quite often so this might again have quite a large performance impact, since we're continuously checking the protection state for any tile entity (I think).

Paper has a more specific BlockDestroyEvent but if we want to maintain bukkit compat this is the only way - performance shouldn't suffer too much, have yet to see the event get called by anything but withers in my testing
