Server Currency & Boss fights

First fully functioning release of the mod. 

-Adds Stevebuck, Enchanted Steve Buck, Economy Diamond, and Enchanted Economy Diamond. (Used as currency among players and for some of the mod features)

-Adds 5 boss mobs: Enhanced Zombie, Zombie General, Zombie King, Void Monster, and Herobrine.

-Adds custom music for the Zombie King boss fight, others to be implemented later on. 

-Adds boss tier system (you cannot jump to Herobrine without going through all the other bosses excluding the Void Monster, which is intended). 

-Made sure that bosses do not spawn in the wild at all, and only by crafting the spawn items for the bosses.

-Intended to make sure the mod is compatible with ProjectE for a certain extent. 

*ProjectE only works with a couple items, primarily the spawn egg for the enhanced zombie as I do not want rare weapons or currency to be created through the very overpowered system that ProjectE condones. 
*Currency is intended to be valued by the players in the server as it may vary depending on what mods are installed.

-Balanced the Zombie King & Herobrine an immense amount of times to ensure the bosses are as long as they should be without being ridiculously difficult.

-Worked out any AI issues as well as texture issues with the mobs as well.

-Added Powerups! (Phoenix down & Mastery Star)

-Removed Herobrine

Next Update: 
-Will add in the ability to have old textures with blocks (Separate block)
-Add in more features, dimensions even, dungeons, structures
