* This class manages highscores and players entries (several players can
* share the same highscores list if the libkdegame library is built to
* support a common highscores file; NOTE that to correctly implement such
* feature we probably need a locking mechanism in @ref KHighscore).
*
* You need one instance of this class during the application lifetime ; in
* main() just insert
* \code
* KExtHighscore::Manager highscoresManager;
* \endcode
* with the needed arguments. Use the derived class if you need to
* reimplement some of the default methods.
*
* This class has three functions :
* <ul>
* <li> Update the highscores list when new entries are submitted </li>
* <li> Display the highscores list and the players list </li>
* <li> Send query to an optionnal web server to support world-wide
* highscores </li>
* </ul>
*
* The highscores and the players lists contain several items described by
* the @ref Item class.
*
* The highscores list contains by default :
* <ul>
* <li> the player name (automatically set from the config value)</li>
* <li> the score value </li>
* <li> the time and date of the highscore (automatically set) </li>
* </ul>
* You can replace the score item (for e.g. displaying it differently) with
* setScoreItem or add an item with addScoreItem.
*
* The players list contains :
* <ul>
* <li> the player name (as defined by the user in the configuration
* dialog) </li>
* <li> the number of games played </li>
* <li> the mean score </li>
* <li> the best score </li>
* <li> the best score time and date </li>
* <li> the player comment (as defined by the user in the
* configuration dialog) </li>
* </ul>
* You can replace the best score and the mean score items
* by calling setPlayerItem.
*
* To submit a new score at game end, just construct a Score, set the
* score data and then call submitScore().
* \code
* KExtHighscore::Score score(KExtHighscore::Won);
* score.setScore(myScore);
* KExtHighscore::submitScore(score, widget);
* \endcode
* You only need to set the score value with Score::setScore()
* and the value of the items that you have optionnally added
* with Score::setData() ; player name and date are set automatically.
