Add rank_members and rank_members_in methods

* Added `rank_members(members_and_scores)` and `rank_members_in(leaderboard_name, members_and_scores)` allowing you to pass in an array of `member_name, score, member_name, score` and so on. Use this method to do bulk insert of data, but be mindful of the amount of data you are inserting since a single transaction can get quite large.
* Bump version to 2.0.5
