Disable automatic on-touch activation of external airlocks (#2385)

* Disable automatic on-touch activation of external airlocks

It's a total pain to reliably get inside a two-door airlock without tripping the firelocks, and that's if you're *intending* to use it properly...

People keep draining the entryway air on the sandbox servers (so people have to crowbar the firelocks open, and this reduces available air)

* Disable automatic on-touch activation of external airlocks: Change auto_open to autoOpen

* Change auto to bump
