Title: Rendered power=substation as the now deprecated power=sub_station.

As per case #230, power=sub_station is now deprecated in favour of power=substation.
While there seem to be efforts to improve the power rendering, this change provides a small stop gap to render the now recommended power=substation.

Can you please consider accepting this pull request until the bigger changes are ready?

Thanks
