EventMud v1.0.1

A quick and dirty migration of SocketMud v1.10 to an event notification library that enables asynchronous socket i/o and scheduled events. It should be used as an example only.

The event notification library is called libevent, and documentation is available at http://monkey.org/~provos/libevent. This implementation used libevent v2.0.1 (alpha) and was tested under Cygwin v1.7.

The main polling loop has been replaced with a dispatch into libevent, and a small set of callbacks to handle socket i/o and a few timers.
