BuildingMMO System / Shield and Siege Timers

"One does not simply walk up and claim a Resource Node." -- Aragorn (probably)

This week we cover further improvements to the MMORPG Kit building system with shield and siege timers applied to the ResourceNodeEntity. Resource nodes are invulnerable to damage when under a Shield timer, and can be claimed after HP has been reduced to 0 which can only happen with an active Siege timer.
