Vote Reward

/*
 * This is a script completely developed by Rain^ (?)
 * You are not allowed to sell any copies of it.
 * Since 2.0 (by Zoey76 for L2J Forums):
 * Added logger instead of System.out.println()
 * Moved to Datapack.
 * Reworked AutoReward class.
 * Reworked getVotes() method.
 * Time is in minutes instead of milliseconds.
 * Uses different amount for each item.
 * Only rewards online players, not offline shops.
 * Rewarded players count.
