Prealpha v0.02 and 0.03

If you've been paying attention, I've tagged Prealpha_v0.02 and Prealpha_v0.03 in the SVN page a few days ago. I will soon be packaging them for download in the main downloads page, but here is a general overview of what's included.

Features:
Application management system
Top-level window management system
A generic window class that you can extend to create your own windows
A debug output system that enables the user to log certain messages if they choose to

Please note that v0.02 uses an error system that was removed in v0.03. v0.03 logs all messages to a file specified by the user while v0.02 incorporates the old messagebox error notifications.
