SEO addon for Journal3 Filter

• Fixed work on product/search when using default seo_url.
• Minor fixes.

What's new:

• Added the ability to exclude entities in the SEO slug generator. For example, if you are not using attributes in a filter, you can exclude them from the overall list and not generate slugs for them.

• Improved the performance of the slug generator: code restructuring, various minor tweaks.
• Improved compatibility with Complete SEO.
