anchor ability on shipyards

i was really wanting to copy this and give the ability to hypergates but i couldn't find anything in the xml. my goal was movable hypergates because if you can move a shipyard that can build a huge ship, why not the hyper gate too? slope game

i may have to settle with removing the admin cost, making it take thulium instead. just worried about the ai over spaming them. If anyone has any other ideas that might work I would really love to hear them.
