Add canonical tag als to CMS and BLOG pages (actually all pages)
Duplicate content is not very good for seo. Would be good if Magento could actually ALWAYS on every page check for the base url and use the canonical tag.
We can already set the canonical tag for products and categories, but not yet for other pages. Now we see duplicate content for these pages

How about we add this to core? Magento 1.8 and/or2.0
