renewCreep not using energy correctly

[chris]

When doing renewCreep, the energy of the very first spawn in this room is used, instead of the energy of the spawn which actually is performing the action.

E.g. Say you built "Spawn1", "Spawn2", Spawn3" in this succession. Now Spawn[2|3].renewCreep will tap into the energy pool of Spawn1 instead of using its own.
