BURN BABY BURN

[Nielesonimusso]

FIRE is so hot right now

• added hot boolean property to indicate an element can burn

• added burn_chance element properties to indicate element can be burned with chance

• added decay_into and burn_into properties to determine what elements turn into when they decay/burn

• added SMOKE and STEAM elements

  • FIRE decays into SMOKE, which decays into AIR
  • WATER burns into STEAM, which decays back into WATER
  • OIL burns into FIRE
