Enhancements to the LPG event system.

[Joe Andresen <joe.andresen@...>]

I made a blog post about some enhancements I made to the Event System presented 
in Lua Programming Gems.

The enhancements have to do with passing event data from C++ to lua.

so  you can do things from C++ like EventSystem->FireEvent("collision", CollisionEvent);

And in lua  have access to that collision event's data.

comments, questions welcome.
