Some improvements in twitter_bootstrap_twitter_bootstrap_btn_dropdown and twitter_bootstrap_preprocess_page

Hello,

I made some improvements to these 2 fonctions. See attached patches (I'm not a patch expert, tried to made them with netbeans on windows, not sure it's ok, I'm allergic to command line and it seems the only viable way to make patches so...). But it's very small patches, easy to apply

The first one in twitter_bootstrap.inc line 134
$output .= l($variables['label']['title'], $variables['label']['href'], $variables['label']);

Don't know why you put $variables['label'] as link options, I think it's a typo, so I corrected it to
$output .= l($variables['label']['title'], $variables['label']['href'], $variables['options']);

The second one in template.php around around line 150 you have

    // Build list
    $variables['secondary_nav'] = theme('twitter_bootstrap_btn_dropdown', array(
      'links' => $variables['secondary_menu'],
      'label' => $secondary_menu['title'],
      'type' => 'success',
      'attributes' => array(
        'id' => 'user-menu',
        'class' => array('pull-right'),
      ),
      'heading' => array(
        'text' => t('Secondary menu'),
        'level' => 'h2',
        'class' => array('element-invisible'),
      ),
    ));

In drupal 7 the attributes array needs to be in an option array. And I added html => true too to make it more flexible (for example I would like to add the user glyphicon before the User menu text in the secondary button, but couldn't because it didn't accept html tags). Here so I changed it like that

    $variables['secondary_nav'] = theme('twitter_bootstrap_btn_dropdown', array(
      'links' => $variables['secondary_menu'],
      'label' => $secondary_menu['title'],
      'type' => 'success',
      'options' => array(
        'attributes => array(
          'id' => 'user-menu',
          'class' => array('pull-right'),
        ),
        'html' => true,
      ),
      'heading' => array(
        'text' => t('Secondary menu'),
        'level' => 'h2',
        'class' => array('element-invisible'),
      ),
    ));

Fell free to review and commit it.
