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.

Remove unnecessary "air" fallback recipe for hoes to avoid this showing
in crafting guides.

Use noises to create a varying mix in coniferous forest biomes:
Areas of large pines only, areas of small pines only, mixed areas.
While also having areas of high and low tree densities.
Saplings grow into large or small pines with equal chance.

Has 'is_ground_content = true'.
Drops 'default:ice'.
