sfinv:
Move license information to create the missing license.txt file.
Make README consistent with other Minetest Game mods.

player_api:
Add missing texture and sound credits to README.
Update and add extra license information.

default:
Remove credit for 'player_damage.ogg' sound.

Previously, maximum flora density was chosen based on the extremely rare
occurrence of all 8 flowers being at high density at one location. This
caused flora everywhere to spread to an unacceptably high density.

Revert the threshold to 3, which in testing results in a more acceptable
maximum density of 7 flora per 9x9 area.

Replaces 'bush' in snowy grassland.

Move chests code out of nodes.lua and into a new file.
Credit torch code, and chest and torch models in README.txt.
Remove 'torches' mod text from torch.lua.
Minor cleanups in README.txt.

Minor clean up of README.txt, including deletion of credits for removed
torch textures.

Previously, boat responsiveness varied greatly depending on server
lag and singleplayer / multiplayer.
'dtime' is the time from the last execution of the boat entity
'on step' function, so must multiply acceleration and yaw change.

Retune acceleration, turn rate and drift deceleration.

Make reversed turn only happen with significant backwards speed.

Dedicated fence rail textures coming in a follow-up PR.

Better pathfinder algorithm, allows tuning the lag spike compensation.
Smoother movement (when it's laggy).
Set the player animation to stand on attach.
Remove driver when they leave.
Only update velocity when it's necessary.

Document controls in README.txt.

Optimise 'get yaw' and 'set yaw' code.

Use a new table beds.bed_position to check if a bed is in use.

These use 'spawn_by' to avoid steep slopes.

To avoid respawn position being possibly very distant from new player
spawn position.

Conf.example: Remove quotes from bones modes. Setting does not work
if quotes are used.

6 gunpowder and 1 paper crafts to 2 TNT stick craftitems.
9 TNT sticks craft to 1 TNT.
TNT stick is not yet usable as an explosive, possibly later.

Alter a few biome y-limits for consistency.

Apples only regrow where they first appear on trees, either on mapgen or when grown from saplings (meaning apples that were placed by players won't regrow).
Once the tree is cut down in full (leaves removed), regrowth will stop.
New apples only grow in daylight, and take the same time as a sapling to grow.

Move previous tundra to highland and remove the snowblocks that are
unsuitable for a fairly dry biome, use snow slabs instead.

Add silver sandstone strata to 'cold desert' biome.
Add sandstone and desert_sandstone strata to 'desert' biome.

Reduce bronze tool capabilities to be between stone and steel.
Swap depths of iron ore and tin / copper ores for corresponding
progression.

Disabled in mgv6 and singlenode mapgens, by setting, or if
'static_spawnpoint' is set.

Cleanup format of minetest.conf.example.

Iron at y = 0 was far too easy to find.
Adjust gold lower region to be twice the depth of highest level, like
all other ores.
Diamond at y = -500 was too easy to progress to.
Make diamond and mese block deeper to create a depth progression from
mese crystal to diamond, to reflect tool progression.
This all creates a satisfying 2^n depth progression, with lower regions
being at twice the depth of highest levels.

This forces all explosions to damage entities within the 1 node
range. If that needs to be disabled, the damage_radius needs to
be set to 0.
