Remove search for 'group:flora_block'
Enable flora spread on 'dirt with dry grass'

Tidy up position numbers and code
Check for flora group aswell
Improve node light check for mushroom growth
Shrooms grow in 3 and below light

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

These have almost no value gameplay wise. Mushrooms spread
by their very nature into appropriate soil nearby, and
harvesting spores is something only scientists do. Actual
mushroom farmers leave a few mushrooms and put on more
manure, and keep the light off.

Modify the growth ABM to test for light levels and attempt
to plant a similar mushroom nearby (+/- 2 x,z, +/- y). Light
at both source and destination needs to be low enough. I've
tuned it to be 3-4 spaces from a torch.

Mushrooms will die in full sunlight, but they can survive under
trees and may grow out at night anywhere.

Removed obsolete textures.

Remove unused nodes and provide aliases for them.

Aliased obsolete nodes so no unknown item nodes appear.

Mushrooms die only in full sunlight (light level 15).

Add 'buildable_to = true' to flowers and waterlily

-> Don't always drop the main mushroom (allowed endless spore generation loop before)
-> Drop less spores, before you got lots of spores

Code re-arranged and clarified

Update

Improved flowers' registration system - Specific nodeboxes, - Color groups - All datas were put into a table then unpacked for add_simple_flower
