[MOD] blogs: Started as a simple html parsing [FIX] on mod-last_blog_posts, but the problem was further upstream (partly involving r41770) where post data was parsed under some conditions connected to wysiwyg.
Now only parsed_data gets parsed (also added parsed_except for similar reasons).
Moved almost all post processing to bloglib->list_blog_posts() and made output more consistent.
Improved perm checking on module_last_blog_posts (more to be done)
Removed useless isHtml param from bloglist plugin and fixed missing author info.
