Feature add etrd stat tracking

[schealex]

This adds tracking of a new stat for EnergyTerminalReceivedDomestic (etrd) for rooms receiving domestic energy transfers from terminals

When I initially implemented this terminal tracking I decided not to implement this because we already have the variant EnergyTerminalSentDomestic, which should encapsulate all transfers that are also EnergyTerminalReceivedDomestic? I don't see why this is useful, unless I am incorrect

[schealex]

well i find it useful because now you can see where the domestic energy is going to. Because the other stat is outgoing from a room but you had no idea where it was going to

Ahh good point, useful for debugging.
