Get access to actual leaderboard entries

[jinjinjinK]

With this wrapper we don't have access to leaderboard entries only the handle of a leaderboard, this handle should be used with DownloadLeaderboardEntries to get players scores if I understand it correctly.

Could it be possible to add this to the wrapper, because having leaderBoard but not being able to show it in the game is not that usefull. Thanks !
