I fixed a bug were players could attack in spectator mode.
Third party plugins should be more compatible with off-hand attacks now, this includes custom enchantment type plugins.
I added dualwield.mine and dualwield.attack permissions which are given by default.
Added an API which allows you to check if BlockBreakEvent and EntityDamageByEntityEvent were done using off-hand actions.
Removed the ability to mine using right click when nothing is in your off-hand. This confused many people and I needed to remove it to implement the API.
