Add brandpage and other minor changes to modified oscommerce webshop

For this modified oscommerce shop, there are a few elements missing. -Add a "brandpage" to the menubar with all the brands. Clicking the brand, should show the productlisting of course. -The difference between a new category and a next line of the same category is not clear. On subcategories it is much more clear. See screenshot category / subcategory. Also change categories "ons assortiment" to 2 columns -Change some menu-text in the administrator.
