Improve responsive display of Published | Last updated post info

[bobbingwide]

For each bit of content in the genesis-oik and genesis-a2z themes the Published and Last updated dates are displayed in a paragraph of class "entry-meta" with a vertical bar / split bar separator before the Last updated label.

At certain display widths it makes sense to display the information on two lines rather than seeing it wrap. This could be achieved by enclosing the split-bar in a stylable span.

    $string .= '<span class="splitbar">';
    $string .= ' | ';
    $string .= '</span>';

The class name of splitbar looks odd. Perhaps it should be "sepbar"

Note: This has already been implemented in genesis-a2z
