made structures either flippable or prevent it completely (#1980)

Foundry is now flippable. SteamEngine is not yet flippable due to collection zone (could use similar solution as foundry).
Pump is not yet flippable, because I don't want to test the bazillion combinations of states of the pump now - maybe after a release.
