Logging

Added support for Rich Text Format output in my logger. I'm not doing anything fancy with it but now my log files are in color, which makes navigating to a line with a warning or error a bit easier.

I started by looking at this tutorial on gamedev, but ended up just downloading the specification from Microsoft and reading through it. It's funny, I can remember when I would have preferred the tutorial, but these days i'd rather just RTFM.
