Syndicate Strike Team and Deathsquad Improvements

- SST and DS members now get advanced magboots instead of combat boots,
with the SST getting ones that share a sprite with the blood-red
magboots.
- SST and DS members now get a fully pressurized double emergency oxygen
tank, as the emergency oxygen tanks they were getting were laughably
inadequate.
- Filled double emergency oxygen tank is a subtype of the 1/3 filled
one, so those are left unchanged.
- SST space suits are now as armored and acid-proof as DS space suits.
- SST space suits are now a subtype of the two specific colored
Syndicate spacesuits they used, so the originals remain unchanged, as
they spawn on away missions.
