Categories based on sonar's tags

@katwchen @brynary I dug a little into Sonar's tags and came up with this approach to build categories. It is related to what @brynary and I briefly talked a few days ago.

This does not look at all tags, it can definitely be improved, but already has a match for at least one tag and category and provides a framework for checking Sonar's rules against our Categories.

This looks like a great start. I think we can roll forward with this and we can always do a another pass of fine tuning if desired later.
