Rules in config effecting other rule's severity when partially matching

[bgriffith]

The use of searchArray in rules.js is causing rules to effect others severity levels. For example this is causing rule foo to effect rule foo-bar as it is partially matched first.

A quick fix for this is to wrap the rule name with a file extension and a leading slash but I'm open to better suggestions!

Another thing to consider is that this will mean it's a lot more strict in that names won't be able to just partially match.
