   @brief
   A class that can be used for access to Blogger  1.0 blogs.
   Almost every blog server supports Blogger  1.0. Compared to
   MetaWeblog  it is not as functional and is obsolete on blogspot.com
   compared to GData which uses Atom instead of Xml-Rpc.

   @code
   Blog* myblog = new Blogger1("http://example.com/xmlrpc/gateway.php");
   myblog->setUsername( "some_user_id" );
   myblog->setPassword( "YoUrFunnYPasSword" );
   myblog->setBlogId( "1" ); // can be caught by listBlogs()
   KBlog::BlogPost *post = new BlogPost();
   post->setTitle( "This is the title." );
   post->setContent( "Here is some the content..." );
   myblog->createPost( post );
