fix a bug in comments. Now all user(admin and author) can summit comments.
all comments will show the user name rather than the user id.
added a view shows all blogs which belong to one author.
change the authorized, only the owner of blog have rights to edit his own blogs, or the admin, who can edit all blogs.

fix some other bugs and upgrade the view.

Next time:
add the 'follow' function for users, which can show his favourite authors and view their blogs.
