Title: Added the score reception functionality - method LoadCurrentScore

For the issue #189
Usage example:

using GooglePlayGames.BasicApi;
...
PlayGamesPlatform.Instance.LoadCurrentScore(
boardID,
LeaderboardConsts.TIME_SPAN_ALL_TIME,
LeaderboardConsts.COLLECTION_PUBLIC,
(IScore score) => { if(score != null) Debug.Log(score.value); }
);

For now, only works on Android as I have no iOS devices. Sorry.
Also, there seems to be a bug of unknown etymology - changes to the scores, issued with the ReportScore, are shown immidiately in the Leaderboards UI, but are delayed for approximately a minute when querying using LoadCurrentState.
