Dev option to disable CacheBuster query strings for easier CSS styling

Hi,

I created a sub theme which add's a Dev option to temporary disable Drupal's CacheBuster query strings after the stylesheet file name (style.css?XYZ). This is useful for live styling with Espresso or CSSEdit for Mac using their great @override feature.

Mabe it could be included in Zentropy core.

theme-settings.php

  $form['zentropy_settings']['zentropy_dev']['zentropy_cachebuster_css'] = array(
    '#type' => 'select',
    '#title' => t('CachBuster CSS query strings'),
    '#description' => t('During theme styling with CSSEdit’s or Espresso’s @override feature, it can be very useful to disable the CacheBuster CSS query strings. (style.css?XYZ)'),
    '#default_value' => theme_get_setting('zentropy_cachebuster_css'),
    '#options' => array(
      '' => t('Add query strings (Drupal default)'),
      'all' => t('Always remove query strings'),
      'onlyadmin' => t('Remove query strings for logged in admins only'),
    ),
  );

template.php

/**
 * Implements template_process_html().
 */
 
// Remove Query Strings from CSS filenames (CacheBuster)
function zentropy_process_html(&$variables) {
  global $user, $conf;
  if (theme_get_setting('zentropy_cachebuster_css')) {
    if (theme_get_setting('zentropy_cachebuster_css') == 'all' || (in_array("administrator",$user->roles) && @$conf['site_offline'] == 0 && !stristr($_GET['q'],'flush-cache'))) {
      $variables['styles'] = preg_replace('/\.css\?.*"/','.css"', $variables['styles']);
    }
  }
}
