Rebalance of space suit/rig helmets.

**Normal space suit helmets no longer conceal your identity nor protect against flashes or welding.**
Use gas masks or sunglasses instead.
**RIG helmets conceal identity and have flash/welding protection depending on what they're used for.**
**Engineering/Advanced RIG helmet have welding protection, the atmos helmet does not.**
Reason being is because the atmos hardsuit is completely fireproof and this can be incredibly valuable. ENGINEERS are supposed to weld in a vacuum, not atmos techs. Atmos techs have welding helmets for non-vacuum welding.
**Combat RIGs (syndicate blood-red, security) and syndie space suits have basic flash protection now, but not welding protection. They are also identity-concealing.**

- Basic gar glasses you can obtain from autodrobes, the orange ones, are no longer flash-protected like sunglasses. The orange captain gars are still flash protected however.
- Meson GARs have the proper attack force and throw force now.
- Death squad space suit properly airtight and biohazard protected.
- Some tweaks to themed space suits like pirate and santa.
- Space helmet sprite is slightly transparent, you can slightly make out a face of who's inside because immersion.
- Atmos tech helmet sprite tweaked to be more revealing than the engineer and advanced helmet because it lacks welding shielding now.
