Boss Refreshed

-Each Boss got a new coat of paint.

-Changed the Ender Dragon completely, now inspired by Lanostry's Red Dragon.

-The Wither received a new model and texture, but it is still very faithful to its original design, just brought to my current standards.

-Same for the Elder Guardian.

-The Warden received a brand new design, fixing its small stature. It's now much bulkier and closer to the vanilla counterpart.
