Update CraftBukkit to Minecraft 1.7.10
Put damage modifiers in Functions for event. Fixes BUKKIT-5681
Handle uniform block ids greater than 127. Fixes BUKKIT-5686
Provide modifier functions to EntityDamageEvent. Fixes BUKKIT-5688
Don't confuse client with sound coordinates outside view distance.
Fix removal of items from Item Frames. Fixes BUKKIT-5736
Fix cancelling PlayerDropItemEvent. Fixes BUKKIT-3313

Up until this commit the PlayerDropItemEvent, if cancelled, would return
items to the first available slot in the inventory - which is clearly
undesirable as a player and plugin author to deal with.

This commit changes that by ensuring that the item is returned to where
it came from in the player's inventory. This still supports modifying the
drop from the player and will default to "first available slot" if the
item has changed since the event was fired. Other remaining behaviour of
the event is still in tact and has not been modified.
Use sensible AssertionError instead of ambiguous RuntimeException
Implement deprecated methods. Adds BUKKIT-5752
Fix PlayerFishEvent not correctly cancelling. Fixes BUKKIT-5396

Prior to this commit cancelling the PlayerFishEvent would cause various
states of the fishing routine to be incorrectly or wrongly fired. This
incorrect behaviour was due to the miscommunication between the server and
client regarding the fishing state. When the event was cancelled, the
bobber entity was removed and caused the client to incorrectly determine
what the "next state" was to logically be.

This commit resolves the issue by ensuring the client is made aware of the
correct changes at the correct time regarding the bobber entity, therefore
keeping the logical steps of "fishing" proper and in-tact.
Modify the invalid item set to permit command blocks. Fixes BUKKIT-4342

When using a "vanilla" Minecraft server using the "pick block" key on a
command block yields the invoker with a command block within their
inventory while in creative mode. Implications of the invalid items set
containing the command block also include having a "ghost" item that
cannot be placed due to it not actually existing.

This commit resolves the problem and brings Craftbukkit closer to vanilla
behaviour by removing the command block item ID, 137, from the invalid
items set.
Implement ability to keep items on death via plugins. Adds BUKKIT-5724

When a player dies their inventory is normally scattered over the the area
in which they died. Plugins should be able to modify this behaviour by
defining whether or not the player's inventory will be dropped on the ground or waiting for the player when they eventually respawn.

This commit implements the methods included in the Bukkit half for the new
behaviour by acting upon the boolean flag. The boolean flag is tested
prior to clearing the inventory as well as prior to dropping the items on
the ground. If the flag is true (indicating "keep inventory"), the items
are not removed from the player's inventory and are not dropped on the
ground.
Allow teleportation of entities on vehicles. Fixes BUKKIT-4210

Up until Minecraft version 1.5 it was not possible to teleport entities
within vehicles. With the 1.5 update came the change in the Minecraft
teleportation logic to dismount before teleporting the entity, if
applicable.

This commit ammends the existing CraftBukkit logic for rejecting
teleportation for entities in vehicles to permit the action. Due to this
change, CraftBukkit is now in-line with Minecraft 1.5 teleportation logic.
