[GNE]New Event System

[Gillius <gi...@ma...>]

I just got through with an 8 hour code-a-thon here working on making a 
completely new event system.  Note that to the user the API to follow is 
the same.  The main difference is now that it WORKS.  It is much cleaner 
now and does a few cool things like:
  Doesn't crash.  Does what it the docs says it does.  It accessed by a 
single thread as is easy to control.

Before there was ONE event thread for everything, and events weren't 
controlled.  One thread can call one function and one thread could call 
another etc.  Sometimes three different threads could be in there and it 
was hard for the user to follow and hard for me to follow.

onDisconnect could theoritically be called before onConnect while 
onDoneWriting was being called and threads sending information while 
another tries to read at the same time.  That is no more.

There is one SINGLE thread that maintains an event queue, one thread for 
each connection.  It serializes the events and actually guarantees 
onConnect always comes once and only once and first and onDisconnect comes 
only once and only as the very last.

This has the additional benefit that GNE can process events for other 
connections at the same time AND do reading as well.  Before almost all 
events and reading was handled by the same thread.  Now it is not.
