Organizing, categorizing and prioritizing patterns

There's enough raw patterns in here to justify organizing the file.
Now that whitespace and comments are supported, I've been dividing it into sections

More critical problems should be near the top as I would rather the script identify a file as a backdoor instead of as a spammer.

I don't know the history behind a lot of these or the implication of the code, so I'm sure I mis-categorized many.  There are also many that I have not done yet.
