server (blog): implemented tag/category filtering:
- the tag=[quoted tag] query is used to use the filtering
- MAM data use request.mam_extra instead of request.extra_dict to avoid using it with item_ids
- getDefaultQueryData function is used to keep query data (link MAM category filtering) between links
- filtering is help when displaying a blog post, this way it's easy to navigate between thematic posts
- filtering can be removed by clicking on user avatar/nick (with default theme)
