Title: add prevent-block-place option

Prevents players from placing blocks outside the world border. Default
off.

This is for the PrisonPearl plugin, where if a player is imprisoned in a
chest placed far enough outside the world border it becomes impossible
to break the chest and free the player.

The BlockPlaceEvent listener is only registered if the option is
enabled.
