Minor Pipebomb shrapnel can go through shuttle walls.

[mbc]

LOS checks for shrapnel are based on sight. (for example if you see a bomb explode on the other side of a window, shrapnel can still hit you).
while it's technically possible, more accurate LOS checks would be much slower than using byond's builtin view() function.

edit : for clarification, shrapnel does not behave as a projectile would. instead anybody within range takes shrapnel immediately on explosion. We could maybe change this part
