- plugin administration: small fix during activation phase

- plugins: added 3 actions in category_cats.inc.php and 1 event that allow a plugin to decide if insertion to #history occurs
- added a warning in section_init if script_basename() is not index or picture (I think we'll have issues on some servers with this function)
- web service methods categories.getImages, tags.getImages and images.search return now the image comment
