Fixed compilation error
Added more parts of the inventory system, this also included a class to merge 2 fixed size lists back to 1 List
Fixed problem with sending of ItemStacks, a empty slot data sends a short and the size of a short is 2 not 1
Added CachedMessage that caches the calls to generate the Strings, this speeds up the repeated calls to toMessageJson()
Made it more clear what operations happens in MergedList
Added support for null compound tags because minecraft renders the items as "+ 3 NBT tags"
fixed ++ on wrong side of variable
Updated PacketOutWindowItems, added constructor & reformatter file
Renamed handler to inventoryHandler & Depraceted inventory field, changed the field visibility to private, added getter
 and updated all references to it to use the getter
Removed a few unused imports inside PacketOutRespawn
Added .equals(Object) & .hashCode()
Removed unneeded tags from ItemStack
Added a few testing items
Added player.world field, this will be used when we support multiple worlds
Added missing constructor
Added .equals() & .hashCode() to ItemStack
Changed structure of Inventories, every Inventory implements the Inventory interface, the DefaultInventory gives the
 default implementation of a Inventory.
Added support for players pressing Q to drop a item, or using a number on keyboard to swap the items on the hot bar.
Still no support for remembering when items are moved.
