[Plugin: Catablog] bug in catablog_show_categories

Hi,

Incorrect html is generated for categories widget. Something like

<li id="catablogcategorywidget-2" class="widget-container CataBlogCategoryWidget">
<h3 class="widget-title">Categories</h3>
<li class="cat-item cat-item-59">..</li>
<li class="cat-item cat-item-59">..</li>
<ul></ul></li>

instead of

<li id="catablogcategorywidget-2" class="widget-container CataBlogCategoryWidget">
<h3 class="widget-title">Categories</h3>
<ul>
<li class="cat-item cat-item-59">..</li>
<li class="cat-item cat-item-59">..</li>
</ul></li>

wp_list_categories either prints the list of categories or returns it depending on argument ‘echo’. Echo is not set to false in the function catablog_show_categories() in catablog/catablog.php.

This should be probably be added to the $cat_args:

$cat_args = array(
	'taxonomy'     => $wp_plugin_catablog_class->getCustomTaxName(),
	'title_li'     => '',
	'orderby'      => 'name',
	'show_count'   => $show_count,
	'hierarchical' => false,
	'echo'         => false,
);

Zachary, thank you for the great plugin!
