Currently when a plugin wants to get the location of something it calls
getLocation() which returns a new Location object. In some scenarios this
can cause enough object creation/destruction churn to be a significant
overhead. For this cases we add a method that updates a provided Location
object so there is no object creation done. This allows well written code
to work on several locations with only a single Location object getting
created.
Providing a more efficient way to set a location was also looked at but
the current solution is the fastest we can provide. You are not required
to create a new Location object every time you want to set something's
location so, with proper design, you can set locations with only a single
Location object being created.

If you use BlockFace in any way, to compensate the directionals being incorrect, you can still have backwards compatibility if you add in the handling in your plugin:
boolean legacyBlockFace = BlockFace.NORTH().getModX() == -1; (and then handle it accordingly)
If you didn't special case your directions to fix what's being fixed here... Hurray! Your plugin should now work.

New events:
- InventoryOpenEvent
- InventoryClickEvent - detects any clicks on a slot or outside the window
- In the creative inventory view, only clicks on the quickbar are detected
- InventoryCloseEvent
- BrewEvent - when a potion finishes brewing
- CraftItemEvent (a subevent of InventoryClickEvent) - fired when taking the crafted item
- PrepareItemCraftEvent - fired just before updating the result slot
Changes to existing events:
- EnchantItemEvent extends InventoryEvent and also has a new whichButton() method
- PrepareItemEnchantEvent also extends InventoryEvent
- FurnaceBurnEvent and FurnaceSmeltEvent now extend BlockEvent (as does BrewEvent)
- PlayerInventoryEvent is deprecated (though it never did anything anyway)
New subclasses of Inventory:
- BrewerInventory
- CraftingInventory
- DoubleChestInventory
- EnchantingInventory
- FurnaceInventory
New methods in Inventory:
- getViewers()
- getTitle()
- getType()
- getHolder()
- iterator() - Yes, inventories are now iterable!
- The iterator is a ListIterator that does not support add or remove
New methods in Player:
- getOpenInventory()
- openInventory()
- openWorkbench()
- openEnchanting()
- closeInventory()
- setWindowProperty()
- getItemOnCursor()
- setItemOnCursor()
Other changes:
- createInventory() methods in Server to make inventories not linked to an object
- ContainerBlock is deprecated in favour of InventoryHolder
- New InventoryView class gives direct access to an inventory window!
- Removed the Slot class which did nothing and was used nowhere
Some small credit goes to Afforess (initial conception of openInventory() methods) and Drakia (initial conception of InventoryOpenEvent and InventoryCloseEvent).

This metadata implementation has the following features:
- All metadata is lazy. Metadata values are not actually computed until another plugin requests them. Memory and CPU are conserved by not computing and storing unnecessary metadata values.
- All metadata is cached. Once a metadata value is computed its value is cached in the metadata store to prevent further unnecessary computation. An invalidation mechanism is provided to flush the cache and force recompilation of metadata values.
- All metadata is stored in basic data types. Convenience methods in the MetadataValue class allow for the conversion of metadata data types when possible. Restricting metadata to basic data types prevents the accidental linking of large object graphs into metadata. Metadata is persistent across the lifetime of the application and adding large object graphs would damage garbage collector performance.
- Metadata access is thread safe. Care has been taken to protect the internal data structures and access them in a thread safe manner.
- Metadata is exposed for all objects that descend from Entity, Block, and World. All Entity and World metadata is stored at the Server level and all Block metadata is stored at the World level.
- Metadata is NOT keyed on references to original objects - instead metadata is keyed off of unique fields within those objects. Doing this allows metadata to exist for blocks that are in chunks not currently in memory. Additionally, Player objects are keyed off of player name so that Player metadata remains consistent between logins.
- Metadata convenience methods have been added to all Entities, Players, Blocks, BlockStates, and World allowing direct access to an individual instance's metadata.
- Players and OfflinePlayers share a single metadata store, allowing player metadata to be manipulated regardless of the player's current online status.
