implement environmental hazards

[surfactants]

need to wait for the detailing system (see #62)

it would be nice to have multiple types per faction, but this should suffice:

• BUGS:
  • acid pools
• PIRATES:
  • weapon traps
• GHOSTS:
  • mining explosives
  • ice floors???????? that's more physics 😞
• LITHOBIOMORPHS:
  • crystal spikes
• ROBOTS:
  • electrified conduits

shaders would be neat here...

[surfactants]

need some sort of flag in the database to determine which details are hazardous.
