see a lot of errors like http://stackoverflow.com/questions/11075507/modernizr-causes-errors-with-jquery-isotope reported in the wild.
and since we're moving to a 100% addtest api seems good to just say that method is core and required.
@SlexAxton what changes need to happen at modulizr level to deal with this? I'd like to get this as part of 2.6 which shoudl ideally ship in the next week
We would just unwrap the addTest stuff. Modulizr can have unknown names and still work, as far as I know.
addTest should be included by default. fixes #619
