Send block updates even when applyPhysics is false.  Fixes BUKKIT-3971
The CraftBlock class is setting bit 0x4 of the update flag when bit 0x2
should in fact be set here. Bit 0x2 means "do updates"; bit 0x4 means
"don't do updates if the world is static, even when bit 0x2 is set".
Correct event handling for dispensing filled buckets. Fixes BUKKIT-4046

We only go through event creation and calling when dispensing filled buckets
if the bucket is able to place its liquid. However, the check for this is
incorrect so the event is not called when a block liquids can destroy is
in front of the dispenser. This commit fixes the check to match the checks
vanilla does when actually using the bucket.

Improve events for new inventory features.  Adds BUKKIT-3859

This commit brings the InventoryClickEvent up to date with the new Minecraft
changes in 1.5.

InventoryDragEvent (thanks to @YLivay for his PR) is added to represent the
new "dragging" or "painting" functionality, where if you hold an itemstack and
click-drag over several slots, the items will be split evenly (left click) or
1 each (right click).

The ClickType enum is used to represent what the client did to trigger the
event.

The InventoryAction enum is reserved for future expansion, but will be used to
indicate the approximate result of the action.

Additionally, handling of creative inventory editing is improved with the new
InventoryCreativeEvent, and handling of numberkey presses is also improved
within InventoryClickEvent and CraftItemEvent.

Also, cancelling a creative click now displays properly on the client.

Adresses BUKKIT-3692, BUKKIT-4035, BUKKIT-3859 (new 1.5 events),
BUKKIT-2659, BUKKIT-3043, BUKKIT-2659, and BUKKIT-2897 (creative click events).
Fix creative ArrayIndexOutOfBoundsException. Fixes BUKKIT-4305

When a Player drops an ItemStack while in creative mode by placing it outside
of their inventory window, the slot number in the packet is -1. The check
that was added to avoid throwing InventoryCreativeEvent excessively didn't
take this into account, and would cause an ArrayIndexOutOfBoundsException to
be thrown when attempting to get the slot specified by the packet.

This change shorts the invocation of player.defaultContainer.getSlot(
packet107setcreativeslot.b) to only occur if the slot id is within the range
of the Inventory.  This prevents attempting to get the slot from a location
that is actually outside of the Inventory.

Fix negative damage from Zombies. Fixes BUKKIT-4193

Currently, the method used for calculating the damage of zombies is scaled
to their health, but it uses the default max health rather than the real
max health value. If zombies have more health than the default max health
value, the amount of damage they deal becomes negative.

This is caused by EntityZombie.getMaxHealth() returning a hardcoded value of
20, which is the vanilla max health for zombies. Rather than using this value
when calculating zombie damage, the call is changed to instead use
((CraftLivingEntity) this.bukkitEntity).getMaxHealth(). This uses the true
maximum health of the Entity. "this.maxHealth" could be used instead of the
aforementioned method, however that creates a very unclear diff, and a
confusing change.
Correct cancellation of InventoryClickEvent. Fixes BUKKIT-4331

Cancelling an InventoryClickEvent for a single click causes the click not
to be processed by the clicked inventory. The server then doesn't
correctly identify their second click as being a double click, causing an
inconsistency between what the Player believes the inventory to be and
what the server believes the inventory to be.

This change forces an updateInventory call whenever an InventoryClickEvent
whose action is NOTHING is cancelled.  Both clicks are considered
PICKUP_ALL, so updating the inventory after the second click fixes any
inconsistencies that could arise between the client and the server.
Fix cancellation for InventoryDragEvent. Fixes BUKKIT-4332

Cancelling InventoryDragEvent causes the placed items to be lost.  This is
because the cursor is set to the result prior to the event taking place,
so the items are removed from the cursor. When the event is cancelled, the
items removed from the cursor aren't placed in the inventory, and are just
lost.

This change sets the cursor back to the original cursor when the event is
cancelled.
