MP Improvements:
* Fixed shift clicks
* Fixed gemming
* Clientside health, mana, and special are forced down to their maximum values after an armour change. They're adjusted properly upon the next update from the server. (this prevents render issues)
* Fix - defense not transmitting with the original player send
* Cooldowns display client-side now. They may need to be better synchronized though.
* Fixed a slight error in the texture coordinate math for monster textures.
* Being stunned now blocks some actions server-side (previously it didnt do anything or was checked only client side)
* Changed how affixes work, making them static generators that must be registered in AffixGenerator.java in the server code
TL;DR: The inventory system almost fully works, and fixed minor bugs
