Star hack fails CSSLint

[ukozdan]

I appreciate that this is probably more of an observation/feature request and that the syntax in question is part of Pure Grids and not just the gruntified version.

The star hack used to target IE7 fails CSSLint, to which some might respond to with "Who cares?", but it is still a hack. Isn't the HTML5 Boilerplate sufficiently established such that IE7 and below properties could be prefixed with a .lte-7 class?

Hacks are a tool. A great way to target IE7 is the star-hack, so we're using that here. We will be dropping IE7 support in Pure for 0.6.0, at which time the star-hack will be removed.
