This reverts commit 5e4a6e8a, and
             commit 60cf3f85.

The original door API rewrite I posted had all rotation disabled using
the correct on_rotate() handler returning `false`. Two subsequent
changes attempting first to enable simple rotation and second disabling
that again changed the callback handler to a boolean `false`, which
is incorrect use in the screwdriver API, and actually allows rotation.

The proper way to disable rotation for facedir nodes it to use a full
callback handler that does `return false`.

TNT removes flammable nodes from the destruction radius and should
remove flames within it too because they lose their fuel and would
be removed by ABM later anyway.

Create a simple triplet table (src1, src2, dst) for all the dye
recipes and group them logically, with a bit of explanation where
they actually come from.

This prunes a lot of recipes from the list, but the old list had a
ton of combinations that did not make any sense, as well as recipes
that were just gross approximations and duplicates, mixing the same
color with itself just to get the same color back, which just wastes
packets at logon.

The list has been checked to allow all colors created from the basic
dyes (flowers+coal) so that all colors can be crafted.

Craft 4 default:sand to default:sandstone.

Previously, 4 group:sand was craftable to sandstone and sandstone was
craftable back into default:sand, allowing silver and desert sands to
be converted into incorrect colour sandstone and yellow sand.

Copy-paste and only remove form-feed characters.

Added as a new mod as it doesn't fit anywhere else.

This is a game play change, so it better suited to
Minetest Game rather than builtin

Fixes #857

Fixes #1364

Require only 1 mese crystal instead of 3.
To make farming in dark locations easier.
To reduce and balance recipe ore cost.

The cost of TNT remains the same

If the boat pos is over limit, 'add entity' will not add an entity,
causing 'boat' to be nil.

I recently made glass footstep and dig gains too low, raise slightly.
Change dirt dug gain from above-maximum 1.5 to maximum 1.0.
Reduce gain of footsteps: stone, dirt, gravel, wood, metal
Raise gain of leaves footstep.

The fuel would remain active even if source went empty, giving
free cook time to newly inserted items. This patch is supposed
to stop this.

Some nodes with the snappy group (wool, glass pane, seeds) were missing
sound when dug with a sword.
Adding the sound causes it to be used for glass pane, so define a 'dig'
sound in the 'node sound glass defaults' table, use the footstep sound.
Adding the sound also causes it to be used for seeds which deliberately
have no dig sound, so add an empty sound override for seed dig.

Reduce the gain of the glass footstep sound which was excessively loud.

Add some freesound members to license.txt.

Handbrake was barely noticeable and fairly useless.
Equalisng with brake rail deceleration makes it more intuitive to use
and easier to judge stopping distance.

This is slightly modified after #1279 - the setting for furnace
timer was removed and hardcoded to 1.0s, which is the old furnace
timer interval.

Previous code:
Used looped sounds without attaching them to objects or playing direct
to players.
The looped sounds are not 'stopped' when players leave the area.
These may be causing the bug where sounds are heard at extreme
distances.
Entering a world with already present flames results in silent flames.
Sounds are often played at a large number of points in a 6 node lattice.
A large fire is reported to cause a high load, disabling the sound code
is reported to help this.

New code:
Optional flame sound to not interfere with ambience mods.
Permanent flame now has sound.
For multiple flames, sound is positioned at the centre of all flames, and
has volume determined by flame number.
The original freesound 'large fire' recording was used to create 3 sounds
that play at random for a non-repetitive effect. At low volume it is
suitable for small fires.

Original sound files and sound function (as an empty function) kept
temporarily to reduce disruption.

Reduce gain of flame extinguish sound.

Also sets creative:all as default inventory page
Fixes #1423

Some GPUs cause visual bugs when mip-mapping is used with indexed textures
that use alpha. Because leaves are sometimes rendered opaque it is even
more important to keep these as RGBA to preserve the correct background
colour.

Papyrus:
Make base node dirt instead of dirt_with_grass. Formerly the exposed
dirt would change to grass but the new grass spread ABM now prevents that.

Waterlily:
Don't specify a water_source node in the schematic, as it may be used in
river water. It was not force-placed but should really be "air" prob = 0.

This changes the farming API such that any nodedef with paramtype2
and place_param2 are passed through to all the plant stages of the
farming plant.

This allows plants to use an alternative mesh for the plantlike
drawtype, and provide a bit of graphical variation in plants.

We enable this for wheat, using place_param2 = 3, which is the '#'
shaped plant mesh. If you would actually be able to give yourself
this plant in creative or through /give, you would also get the
same '#' shape.

This makes all the 3d torch selection boxes 1px oversized. Before,
they were inconsistently sized and too small for the upright torch.

Biomes:
Add 'sandstone desert', 'cold desert', 'snowy grassland'.
Rename 'glacier' biome to 'icesheet' biome.
Rename non-swamp 'swamp' biomes to 'shore' biomes.
Remove 'sandstone grassland' biome.
Rename 'stone grassland' biome to 'grassland' biome.
Edit biome points for improved similarity to Whittaker classification.
Change 'tundra' to bare stone with snowblocks.
Make dirt 'swamp' / 'shore' less deep.

Ores:
Make dirt blob ore biome-specific, limit to dirt biomes.

Decorations:
Make mushroom noise spread match that of appletrees as originally intended,
to have mushrooms spawn in darker thicker forest areas.
Add coral reefs in warm oceans.
Add bushes and acacia bushes.
Jungletrees in deeper water for larger swamps.

Register flower mod decorations in singlenode mapgen for use by
minetest.generate_registered_decorations, as in default/mapgen.lua.

Boats:
Previously, boats were not added to inventory in creative mode, fix.
In creative mode multiple boats will not be added to inventory.
Add comment.

Carts:
Set speed to 2 if punched by a non-player, to match the effect of a
player punch.
Add comments.

Fixes (I hope) #1420 (bad method call).

This commit makes the carts mod not add the cart
item to the player's inventory if running with
creative mode and the player already has it.
