Add hook into Vault-Plugin to enable payment-rewards

[FeaRiTail]

Another idea came up (http://dev.bukkit.org/server-mods/safari/?comment=9)

Could you have it hook with Vault so at the end of each Safari it could give $ payouts?
It could also be very useful for giving $ payouts for taking 1st Place in time stats.
