Framework update

I worked on the framework yesterday. I added more to the event and windowing frameworks to pass button presses to windows. If the cursor is visible it passes the button presses to any window and any children components that fall under it.

I gave the button an on click event handler and made it create a new window with a label in it above the original window. It all seems to be working pretty well.

Next I think I need to create some more components to allow me to build the game window from.

Edit: Part of the problem that I'm hitting is that Lua doesn't really have a concept of classes and so has no concept of "constructors". A lot of the things that I am doing would be a ton easier if I could write constructors. I am also having to fake out "virtual" functions to make some of the event handling for windows work properly.
