Main content columns dependent on existence of sidebar

[coheractio]

First of all, thank you for this theme. Very flexible and easy to work with.

I suggest the following change to support the existence or not of the sidebar.
In the various template files, replace :
<div class="small-12 large-8 columns" role="main">
by :
<div class="small-12 <?php echo ( is_active_sidebar() ) ? 'large-8' : 'large-12' ?> columns" role="main">

This could really be handy.
