Merged CMS_BLOG_CONFIG with CMS_BLOG_API. In CMS_BLOG_API, prefer argument of type CMS_USER, rather than using directly user id. Added a CMS_EDITOR_CONTENT_FORMAT for now, to be the format editable by the WYSIWYG editor. Added CMS_MODULE.is_initialized: BOOLEAN to equip router, and module_api with expected preconditions. Fixed typo, especially in log output. Corrected a few routine names such as add_authors that should not be a function according to its name. Converted various function returning html content, to procedure appending html content to an output string to minimize temporary string object creation. Cosmetic: added spaces to make code easier to read, and indentation.
