When a player votes for playerserver, the vote reward command executes.
But if the server is offline, then the vote reward command doesn't happen and player never get reward for vote.
To fix this issue, there should be a voting reward queue for every playerserver. This should store the players that have voted for the server since the last time the server went offline. When the server goes online, voting reward command should be executed for all of the players in the voting reward queue.
