Bootstrap 3 dropdown hover support

It is possible to use the solution mentioned in #16 with Bootstrap 3 as well. Since Bootstrap 3 is the current version and more likely to be used from now on I am forking the issue to 7.x-3.x because I am sure many people will run into this problem mainly because Bootstrap framework developers seem to want to change the current user behaviour on the web rather then support the behaviour itself.

In any case I was able to implement the solution from #16 into Bootstrap 7.x-3.0 with the code bellow added to my template.php. However, the problem is not completely solved because on Desktop it works beautifully and hover, and follow the menu href works as expected.
In mobile it doesn't work for 3 level menu's in a sense that Parent and First Child work with 1 click to open if children present and 2 clicks to navigate to the page itself, unfortunately I have not been able to make it work with second child because once the first child is clicked once it will navigate to the page it links to instead of opening the next level in the menu.

So here is the first half of the solution for Bootstrap 3 hopefully someone will respond with the second and final half of the solution.

function YOURTHEME_menu_link(array $variables) {
  $element = $variables['element'];
  $sub_menu = '';

  if ($element['#below']) {
    // Prevent dropdown functions from being added to management menu so it
    // does not affect the navbar module.
    if (($element['#original_link']['menu_name'] == 'management') && (module_exists('navbar'))) {
      $sub_menu = drupal_render($element['#below']);
    }
    else{
    unset($element['#below']['#theme_wrappers']);
    $sub_menu = '<ul class="dropdown-menu">' . drupal_render($element['#below']) . '</ul>';
    $element['#localized_options']['attributes']['class'][] = 'dropdown-toggle disabled';
    $element['#localized_options']['attributes']['data-toggle'] = 'dropdown';
	$element['#localized_options']['attributes']['data-hover'] = 'dropdown';
	$element['#localized_options']['attributes']['data-delay'] = '100';
	$element['#localized_options']['attributes']['data-close-others'] = 'false';




    // Check if this element is nested within another
    if ((!empty($element['#original_link']['depth'])) && ($element['#original_link']['depth'] > 1)) {
      // Generate as dropdown submenu
      $element['#attributes']['class'][] = 'dropdown-submenu';
	  $element['#localized_options']['attributes']['tabindex'][] = '-1';

    }
    else {
      // Generate as standard dropdown
      $element['#attributes']['class'][] = 'dropdown';
      $element['#localized_options']['html'] = TRUE;
      $element['#title'] .= '<span class="caret"></span>';
    }
  }
  // Set dropdown trigger element to # to prevent inadvertant page loading with submenu click
   $element['#localized_options']['attributes']['data-target'] = '#';
  }
  // On primary navigation menu, class 'active' is not set on active menu item.
  // @see https://drupal.org/node/1896674
  if (($element['#href'] == $_GET['q'] || ($element['#href'] == '<front>' && drupal_is_front_page())) && (empty($element['#localized_options']['language']))) {
    $element['#attributes']['class'][] = 'active';
  }
  $output = l($element['#title'], $element['#href'], $element['#localized_options']);
  return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . "</li>\n";
}

rest of the magic is done by https://github.com/CWSpear/bootstrap-hover-dropdown which is probably the most widely used "unofficial" Bootstrap Plugin
