Pocketmine-mp: Enchantment: Unbreaking forgotten slot

[TheAz928]

I've noticed, when registering "unbreaking" in Enchantment.php, there's no Enchantment::SLOT_SWORD on both primary and secondary item slots.

I think it's a very easy to fix and should be fixed.

This issue is not related to game play nor features, so why should I use template?

I think the issue templates are garbage. GitHub should introduce a more interactive way to create issues.
