This reverts commit 77545557.
Due to recent engine commit boats now collide with 'ignore' nodes.

Switch y_max and y_min for flowers, fireflies and default

Avoid hard-coded player inventory lists.
Expose `bones.player_inventory_lists` for mods to look up or change,
which player inventory lists are being dropped or placed into bones.

Acacia bush: Create a unique form different to normal bush, with more
leaf nodes at top than at base.
Acacia tree: Maximum height increased by 1 node. 2 extra nodes of
height variation.
Jungle tree: Add an extra node of height variation. Y-slices moved
downwards to be more balanced between trunk and branches, makes
branches more common.
Pine tree: Increase maximum height by 1 node. Add an extra node of
height variation.

Update sapling 'on place' protection checks for acacia and pine trees.

Height 20 to 32 nodes.
Dependent on chunksize >= 5.
Base limited to maximum altitude y = 32.
Craft sapling from 9 jungle saplings.

At world edge make boat bounce back into world by inverting speed.
At world base avoid falling into ignore by setting y velocity to 0.

Use noise with 1 octave and flag 'absvalue' to create sand paths
in dunes.

Greyer, lighter, reduce lines, remove dark patches.
Shorter and more consistent side texture.

Match maximum spread density to maximum mapgen density for flowers.
Place 3 flora nodes at once instead of 1.
Change ABM chance value to 300 to match previous spread rate.
ABM becomes 3 times less intensive.

Add compatibility code with deprecation warning.

Unbind table groups for base block, stairs, slabs.

Use 128px textures with a slight blur to reduce distortion caused
by formspec texture scaling.
Cross is shifted slightly up and left to compensate for formspec
button image shift.

Previously, saplings were not growing if the dirt they are on turned to
'dirt with snow' before growth.
Also for consistency with other dirt nodes.

Adjust selectionbox width for a better fit and consistency with other
grasses.

This was triggered when too much time had elapsed when timer was called.
Also, fix timer resolution giving free fuel time.

Remove flowers from coniferous forest.
Add 'dirt with coniferous litter' to farming mod overrides.
