New areas for engineering remap

- Also moved hallway from Caels Rust areas.dm file to main Space Station 13 areas.dm file
Removed ID requirement for gas filters

So they can be used in other areas of the station (like toxins and the engine room) without needing atmos access to change settings.
Crate and closet updates

- Added atmos themed sprite for atmospheric technician secure closets
- Added a second radiation suit to radiation suit closets
- Added a solar pack crate (because adding crates to the map with this many objects manually is silly)
Sprite additions and updates

- Fixed passive gate sprite (east and west "on" sprites were reversed)
- Added new Supermatter manual sprite (it glows!)
- Added some floor variants (loading outline for plating - in yellow and aqua, caution stripes for old floor tiles, and yellow and grey checkered floor tiles)
