This adds a 'creative' privilege to survival servers which OPs can bestow
on admin or competent builders to give access to the creative inventory.

Really large books just waste hard drive space and the engine is not designed to
handle that much data in item metadata, this can cause strange things to happen.

No longer have 2 recipes for stairs, choose the one that matches the appearence
in inventory (stair rising toward the right).
Helps to reduce recipe count now that an increasing number of stairs are
being registered.

Alter the wooden trapdoor side texture, replacing the white area with a
repetition of the wood pixels.
It is now consistent with the steel trapdoor side texture.

Derived from the white dandelion texture.
Uses the flower head colours of the previous yellow dandelion.

This reverts commit e523c3a2 to re-enable
the overriding and redefinition of these global functions.

The color autogeneration algorithm of minetestmapper otherwise
causes this node to appear as solid black.

Action of some abm's call functions directly, instead of calling the function inside a function.

This keeps the filenames the same, but adds a new "inside" double texture
for the open chest.
Use regular drawtype for closed chest and delete the "cube.obj" model.
X-flip the right-side texture for the closed chest.

Revert the new 'default:game' inventory back to the old 'main' and use the
lbm to restore the contents of the chest.
Change the name of the conversion LBM to ensure it is run again on already
converted chests.

This is needed because you can't place a node above a bush stem when you are pointing at the bush stem.

The back side had a UV mapping issue which caused the bottom
rear part to "shrink" when opened.

Prevents generating ugly looking dummy images for mods that weren't updated yet.

The previous behaviour is kept as fallback for compatibility, for when the on_ignite
is not defined in the node.

Adds a mesh model that appears when a chest is opened. The chest
stays visibly open as long as the player keeps it open. When the
player closes the formspec, the chest returns back to the closed
shape. While opening and closing, a sound plays.

A second person inspecting the chest will trigger a second sound
open. However, only after the last player closes the chest, does the
chest actually visually close and is the sound close played. This
keeps mesh updates to a minimum.

While it's possible that a server shutting down may cause chests
to remain open, this does not affect the chests' working matter,
and opening or closing them should fix them.

Old chests are converted to the new style by LBM. I previously
had them converted on open but this was unreliable, and LBMs
don't have that problem.

Open chests cannot be dug up. This prevents people from keeping
a chest open and digging it out as well, since closing a chest
would place a chest back (swap) at the spot. We could protect
against this, but it still messes up the client and causes a lot
of "missing node inventory" error messages otherwise. It's
unlikely but possible that a player lagging out causes a chest
to stay "open" and thus unremovable by digging, but there are
other ways of dealing with that - a server restart fixes that
issue.

If the lid of the chest is obstructed, the sounds continue to play,
but the lid isn't opened. Obstructed means that a node is present
above the chest lid, however, we ignore several node types like signs,
torches (not 3d) and wallmounted nodeboxes (typically signs) since
they don't pose any major obstruction in almost any case, and are
typically found above chests. Additionally, the selection box of the
opened chest does not include the lid, and so one can still interact
with e.g. a sign behind an open lid.

Due to the fact that chests now have 7+ textures, we can no longer
use materials (limit: 6) to texture the chest, and so there is now
a single UV mapped image that applies both to open and closed chests.
While this does mean texture pack makers need to create it, this
is extremely simple and consists of a simple cut'n'paste over the
template and should be really easy to do. Only one texture file is
now then used for both open and closed chests.

Due to door items being the thing that's placed, we need to
explicitly play a sound when placing a door.

Fixes #1363

Changing the book page caused the entire itemstack meta to
get wiped due to improper calling of meta:from_table().

Fixes #1711

We have enough gray recipes, but brown is more difficult.

Fixes #1710

Previously i had matched ore density to moreores, but this density was
too high and out of balance with MTGame, reduce density to be similar
to copper ore.
The 2 levels of underground ore were overlapping, fix.
Textures are actually by kilbith, update credits.

Also credit kilbith for bronze, copper, gold and steel blocks, credits
had not been updated at the time.

Use Calinou's textures from moreores mod.
Craft bronze from tin and copper instead of steel and copper.
Match ore density to the moreores mod but start ore at a depth of
y = -32 to be part of the depth progression of other ores.

As written in game_api.txt.

Commit 73d61cbb103415c9a3970eaf2c48aeadabfff828 makes skeleton keys
craftitems rather than tools, warranting the move from tools.lua
to craftitems.lua.

Allow skeleton keys to be stacked by converting them to craftitems and
adding a few lines of code to add a new itemstack to the inventory with
the new key or drop it at the player position if the inventory is full.

Seems like this was a typo

Bush saplings grow in half the time of tree saplings.
Bushes do not need 'from sapling' schematic variants because only the
stem node is force-placed in the mapgen schematic, so only the sapling
is force-replaced.
Bush leaves drop saplings with a rarity that ensures at least 1 sapling
per bush on average.
