exciting things

Laser pointers and overcharged flashes.  Fire fix, some other fixes.  Greater detail in individual commits.  Also, this describes only the first commit.  Might make more by updatetime so.  

second commit: modular guns.  nerfed hardsuits so you can't spacewalk as easily without a helmet.  nerfed pressure damage down to 4 to compensate though.  still deadly.  just less.
