Make Saltern driveable (#4257)

* Broadphase refactor (content) * Shuttle jank * Fixes * Testing jank * Features and things * Balance stuffsies * AHHHHHHHHHHHHHHHH * Mass and stuff working * Fix drops * Another balance pass * Balance AGEN * Add in stuff for rotating shuttles for debugging * Nothing to see here * Testbed stuffsies * Fix some tests * Fixen test * Try fixing map * Shuttle movement balance pass * lasaggne * Basic Helmsman console working * Slight docking cleanup * Helmsman requires power * Basic shuttle test * Stuff * Fix computations * Add shuttle console to saltern * Rename helmsman to shuttleconsole * Final stretch * More tweaks * Fix piloting prediction for now.
