duplicate class entry for pseudo state hover

[csrow]

Just started using the sassy buttons.

In _sassy-button-pseudo-state.sass

I noticed that :hover, "text-decoration: none" is outside of the conditionals and Sass does not combined them after processing the mixed in.

This generates two entries for the class:hover; one containing only one line and the other which contains the main definition.

I repeated the single line within the conditionals just to get rid of the double class entry. I couldn't think of any other way.
