Small bug fixes!

Fixes

• Long standing Mixin Conflict for Living Entity has been fixed due to the help of MarkusBordihn! Should hopefully no longer crash when used with mods like Easy-Npcs and the like.
• You are now able to use offhand items like Shields while using any type of sword. This was due to a single line of code that I had mixed up, oops!

As an aside, thank you all for all the downloads! I have inlcuded Bokoblins as a creative only thing for now as I continue to work on the update!
