Hide category description in Product Categories layout in BE

[yakkes]

The category view in the BE is almost useless when you have a few hundred categories with a lot of text & images in the description.

This quick fix brings back the view from VM1.x (without the tooltip)

Change line 212 in administrator/components/com_virtuemart/views/category/tmpl/default.php  (VM v2.10)
From                <?php echo $cat->category_description ; ?>
To               <?php echo substr($cat->category_description,0,60); ?>
