Shorten product URL - without category

With this change, the URL is shortened as soon as the customer comes to a product.

The categories are displayed normally. Example:

The category link
https://www.shopbetreuung.com/Software-Module/Filtern-und-Suchen:::153_179.htm

remains the same! This is because the category often contains important search terms.

The product link
https://www.shopbetreuung.com/Software-Module/Filtern-und-Suchen/Attributfilter::459.html

changes to

https://www.shopbetreuung.com/Attributfilter::459.html

If a customer or search engine still uses the old link, it will be redirected to the new link.
