event_loop v2.0.2

The event_loop class is a typical event loop that supports C-style callbacks and C++-style listeners except it is not tied to any particular toolkit. Instead, it can be used standalone to implement Unix servers, for example. To compile event_loop, you will also need the cgul source. I really wanted to include the event_loop class in cgul, but the ability to multiplex I/O is not portable.
