API addition - adds reset deaths on new island (#817)

* API addition - adds reset deaths on new island

BentoBox currently tracks deaths in the worlds but the current API only
allows them to be reset when a player joins a team. This setting enables
deaths to be reset when a player starts a new island or resets an
island.

WARN: This should be the only additional WorldSetting we need for deaths.
