Handle the newly refactored minecarts.
Remove duplicate place logic for snow. Fixes BUKKIT-3756
Always consume bonemeal when used on a sapling. Fixes BUKKIT-3755

In Minecraft 1.5 saplings do not grow with a single use of bonemeal anymore.
Our code assumes they will and only takes away bonemeal from the player
when the tree grows successfully (not cancelled by a plugin). Instead we
now always remove a bonemeal even if a plugin is the reason a tree didn't
grow as this matches the vanilla logic more closely.
Limit mob names to 64 chars to avoid client crash. Fixes BUKKIT-3753
Don't set health directly, will interfere with scoreboard system.
Use Chest block state for trapped chests. Fixes BUKKIT-3762
Ignore invalid inventory slots. Fixes BUKKIT-3737
Filter data for items that shouldn't have it and filter wool.

We used to fall Item.filterData() for this but that method is meant for
converting item data to block data during placement and does the wrong
thing for this case. Instead we just see if the item should have data and
if not set it to zero. We also have to filter wool data explicitly because
clients crash when given invalid wool data.
Filter negative values for all items.
Comment out vanilla debug message.
Allow data on tool items. Fixes BUKKIT-3773

Netty

 Implement an uber efficient network engine based on the
 Java NIO framework Netty. This is basically a complete rewrite of the
 Minecraft network engine with many distinct advantages. First and foremost,
 there will no longer be the horrid, and redundant case of 2, or even at
 times, 3 threads per a connection. Instead low level select/epoll based NIO
 is used. The number of threads used for network reading and writing will
 scale automatically to the number of cores for use on your server. In most
 cases this will be around 8 threads for a 4 core server, much better than the
 up to 1000 threads that could be in use at one time with the old engine. To
 facilitate asynchronous packet sending or receiving (currently only chat), a
 thread pool of 16 threads is kept handy. == Plugin incompatibilities As a
 side effect of this change, plugins which rely on very specific
 implementation level details within Minecraft are broken. At this point in
 time, TagAPI and ProtocolLib are affected. If you are a user of ProtocolLib
 you are advised to update to the latest build, where full support is enabled.
 If you are a user of TagAPI, support has not yet been added, so you will need
 to install the updated ProtocolLib so that TagAPI may use its functions. ==
 Stability The code within this commit has been very lightly tested in
 production (300 players for approximately 24 hours), however it is not
 guaranteed to be free from all bugs. If you experence weird connection
 behaviour, reporting the bug and steps to reproduce are advised. You are also
 free to downgrade to the latest recommend build, which is guaranteed to be
 stable. == Summary This commit provides a reduction in threads, which gives
 the CPU / operating system more time to allocate to the main server threads,
 as well as various other side benefits such as chat thread pooling and a
 slight reduction in latency. This commit is licensed under the Creative
