ANSI color codes now reset text attributes. Fixes BUKKIT-3508

The client resets all formatting after a color code is received, but currently the ANSI codes do not, and so the console does not accurately reflect the appearance of the formatted text. Instead, the ANSI color codes are now set to reset all text attributes.
BungeeCord Support

- Allows BungeeCord to set the players real IP address very early in the login process, so that the BungeeCord proxy IP is never even seen by a plugin.
Add oreobfuscator for Spigot.

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
