Because the fire nodes are not removed 100% when there are
no more burnable nodes nearby, they can potentially stay around
for very, very long times, leading to ABM trains every 5 seconds
for no good reason (only 1 in 16 will be removed every interval).
A much better method to remove fire nodes is to remove them by
timer, and give removal a 100% chance if no flammable nodes are
adjacent. This makes fire cleanup a lot faster and more natural,
and will reduce the amount of ABM hits making fire overall more
responsive.
We also remove the 1 in 4 chance and fold the removal of flammable
nodes into the ABM chance.
There's some low hanging fruit cleanups in here as well.
Spread ABM intervals evenly across 1 to 16 seconds
16s ensures no nodes are missed when player walks past
Adjust chance values to compensate, for identical action rates
Combine lavacooling ABMs into one, return to chance = 1
Grass growth: add 'neighbors = "air"' to avoid
processing the thousands of underground dirt nodes
Grass death: Reduce action rate to that of grass growth
Fire: Use chance = 1 for flame extinguishing
and flame removal when mod is disabled
Rename in game.conf and documentation
Update game_api.txt documentation for bucket API and tree functions
Fix tab, space and comment formatting in game_api.txt
Rename in mod READMEs
Add extinguish sounds (from default mod lavacooling)
'disable fire' setting extinguishes fire quickly using a dedicated ABM
'disable fire' also disables all other ABMs
Simplify flammable node removal ABM
Speed up node ignition, it was too slow
Add 'sunlight propagates = true' and 'paramtype = "light" to flame
Balance fire sounds' gain
