iOS & Google Play: Implement next step for global leaderboards

Currently in 0.3.6c, insufficient information is being sent to the leaderboard web server regarding account information for the upcoming leaderboard webpage.

Server currently sends back to the client:

4:16:40, Frame 46230, LOG »  LeaderboardEntrySubmitter_iOS.OnUpdate: WaitingForResponseFromWebServer: Entry submitted to web server successfully.
webRequester.Response: SUCCESS_ENTRY_SUBMITTED_OKAY

WARNING_NOT_ACTUALLY_SUBMITTED__NO_TRANSACTION_HASHES_RECEIVED

SqlLeaderboardUser::__set_state(array(
   'userDisplayNamePersona' => 'XXXXX',
   'steamAccountID' => 0,
   'googlePlayTransactionIDHash' => NULL,
   'appStoreTransactionIDHash' => NULL,
   'itchLoginKeyHash' => NULL,
))

Now that the game is more live and active, can start implementing proper processes.

Tasks:

[ ] Make iOS and Google Play clients upload more info to the server.
[ ] Make server receive and process leaderboard entries properly.
