Toggle case sensitivity for Paid Search Detection

[#1]

Personally, I would prefer paid search detection to never be case sensitive, but I can see why some people might. If I have a 4-letter param (skid, for example) there are theoretically 16 different options of case sensitivity I might want to catch (SKID, SKId, SKid...) and it sure would be nice if I didn't have to figure out and input all 16 of those options. I could check a box to signify if the param is case-sensitive or not, that would be ideal. But really, anything omniture could do to make it easier to deal with case sensitivty in params would be great.
