Hiccup conversion uses the class shortcut

[danieroux]

An option to have the conversion do this:

[:div {:class "main-content large-9 columns"}]

instead of the shortcut:

[:div.main-content.large-9.columns]

Background: nosco/hx#29

[cursive-ghost]

This is fixed as part of #2420 - there's now a config option allowing this.
