Correctly handle wrapped server pings with no favicon.

14c69e294a Correctly handle wrapped server pings with no favicon.
In the current ProtocolLib release (3.1.0) the getFavicon() method will
throw a NullPointerException if the server is not sending a favicon.
This was partly fixed in 3c5482f but there's still no way of checking if
the server is sending a favicon, without checking if the encoded output
of the CompressedImage.toEncodedText() will return a valid result.
This commit will make the favicon getter and setter in the server ping
correctly handle pings with no favicon, by returning null for
getFavicon() (if no favicon will be displayed) and allowing to hide the
favicon by setting the favicon to null.

e56c0fec00 A possible fix for a rare but game-breaking deadlock.
Calling remove() in the main thread will block the main thread, which 
may lead to a deadlock:
    http://pastebin.com/L3SBVKzp

ProtocolLib executes this close() method through a PlayerQuitEvent in 
the main thread, which has implicitly aquired a lock on 
SimplePluginManager (see SimplePluginManager.callEvent(Event)). 
Unfortunately, the remove() method will schedule the removal on one of 
the Netty worker threads if it's called from a different thread, 
blocking until the removal has been confirmed.
 
This is bad enough (Rule #1: Don't block the main thread), but the real 
trouble starts if the same worker thread happens to be handling a server
ping connection when this removal task is scheduled. In that case, it 
may attempt to invoke an asynchronous ServerPingEvent 
(see PacketStatusListener) using SimplePluginManager.callEvent(). But, 
since this has already been locked by the main thread, we end up with a 
deadlock. The main thread is waiting for the worker thread to process 
the task, and the worker thread is waiting for the main thread to 
finish executing PlayerQuitEvent.

TLDR: Concurrenty is hard.

acea92ef5c Switch to using PacketType in the built-in commands.
The format is now as follows:
    /packet add server play 0-255.
    
It may be possible to look up packet types by name later.

6bd8bd2ca2 Handle plugin reloading properly, uninjecting all player channels.

5805150d8c Call the updated player instance in the temporary player.
This allows us to provide additional information to our PacketEvent 
(mostly OfflinePlayer information), without sacrificing sendMessage() 
or getAddress(), which doesn't work in CraftPlayer during login.

9d972b90ac Update the player instance during PlayerLoginEvent as well.
This ensures that we at least have an OfflinePlayer when certain
packets are intercepted, instead of the TemporaryPlayer created 
by ProtocolLib.

9b349299a0 Significantly reduce the possibility of a race condition.
The vanilla server bootstrap (ServerConnectionChannel) is executed 
asynchronously when a new channel object has been registered in an event
loop, much before it is ready to accept a new client connection. It is 
here the whole channel handler pipeline is set up, along with a 
NetworkManager responsible for reading and writing packets. 

The trouble starts when the bootstrap class adds the created 
NetworkManager to a list (f) of managers in  ServerConnection. This list
is regularly inspected by the main thread (in order to process packets 
on the main thread) and includes a clean up procedure 
(ServerConnection#61) in case it detects a disconnected network manager.

Unfortunately, the network manager IS considered disconnected for a 
moment when its added to the list, so the main thread MAY end up 
getting to the network manager before Netty has connected the channel.
This is still very rare under normal circumstances, but because 
ProtocolLib does a lot of initial processing in the channel handler, the
asynchronous thread gets hold up for a long while the first time a 
player connects to the server, allowing the main thread sufficient time 
to catch up and evict the network manager.

The partial solution here is to synchronize on the network manager list,
stopping the main thread from processing network managers when we are 
preparing our new connection. 

But I suspect the best solution would be to correct the root of the 
problem, and correct the race condition in the server itself. This 
could be done by only adding the network manager when the channel is
active
(see ChannelInboundHandler.channelActive).
