SQL Comments in sqlutils.

At this point, my fork can handle standard SQL comments (lines that start with --) and comments that I am calling SQL Roxygen comments (lines that start with --'). I still can't handle comments of the /*  */ variety. But, I can handle the easy comments.

This also pulls some of the files apart, to reduce complexity in the files. I was having a hard time keeping things straight, but if you don't like that part, feel free to ignore it.
