As a site builder, I want the govcms_zen theme to be fully responsive

[kristyacquia]

It looks like govcms_zen has some CSS styling that is hard coded to a specific weight. This looks to be an issue when removing a sidebar region and wanting the left content to be full width, as this is not possible to achieve without custom theming in a customer's own stylesheet for their theme.

See the below for an example;

@media (min-width: 980px)
govcms_styles.css?ovsgop:647
#content {
    width: 660px;
}

As govcms_zen, is a base theme off Zen, I'd like to request that changes are made for this theme to be responsive and using the grid framework.
