Remove that * selector

I'm talking about this:

Asterisk selector is shiet, it's slow and often unpredictable. It also have specificity issues ( specificity 0 0 0 0). Use replacement used in normalize.css for instance (manually selecting every needed element). The even better way is to make asterisk() sass mixin.
