Engine refresh

Utilizes the new omni-filters.
Adds some protective grills outside the engine room, like solar panels have, may have left a hole where meteors tend to pass through >_>
Made sure the supermatter doesn't snag into anything on the way out.

Utilized an atmospheric-like setup for the engine core.
The engine monitor computer can now be used to setup the core, similar to how it's done in atmospherics.

These changes have led to less pumps (in and out of the engine) but people still need to remember to set the filters' target pressure.

Seems to work well enough in my tests but trying to break the setup won't be a bad thing.
