* Unused variables
* Unused values (assigned to variables, but overwritten before use)
* Defining already defined variables instead of reassigning to them.

No longer require night to be skipped for resawn position to be saved
Remove constant beds.read_spawns() calls when a player joins as this
is only required once

Instead of using voxelmanip use 'find nodes in area' instead

Remove spaces inside curly brackets
Split lines over 90 columns

- Only remove the TNT craft recipe, tnt:tnt node and the ABM
- Leave tnt:tnt_burning available for explosions in 3rd party mods

Preserve overlapping registrations of large and small clusters
below y = -64 but now extend the small clusters up to y = 0 (the
previous highest iron ore level) in a similar to way to coal

Each ore's rarity is equal to that occuring below y= -1024

Re-order registrations
Add and improve comments
Change sand blob ymax to 0 as sand does not always rise above 0
Remove dirt blobs from sandstone as it is unsuitable for
many sandstone biomes and ugly in stony sandstone desert
Change ymax of first iron region to 0

- Placing liquid inside a protected area no longer returns an empty bucket
- Remove on_place function, tidy up code, return proper itemstack
- Shorten code (changes from HybridDog/patch-35)

- Global functions sethome.set(name, pos) , sethome.get(name) and sethome.go(name)
- Tidy: trim coords to one decimal place and write to table and output table in one go.
- Add error checking
- Add t4im's homepos loader

When waterlilies are placed near river water source make flowing river
water remove waterlilies instead of flowing around them in an ugly way

Changed node sounds for steel door/trapdoor to stone
defaults instead of wood defaults

Improve registration format
Fix groups not matching corresponding full node
Improve some descriptions

Make it consistent with the slab recipe which conserves volume

Arm and leg textures are now edge-consistent

Previously waterlily has misaligned top and bottom textures and looks
different when viewed from below.

This also hides the flower in bottom texture.

Allows for more properties to be passed through. Somewhat simplifies
the code as well.

This doubles the fall height without damage to 11 nodes.

Allow many crafted nodes to be rotated in any way possible.

These blocks all have slab and stair versions, which can create awkward
patterns if placed together. By allowing these to be rotated players
can create new patterns and appearances that were not before possible.

Since this wasn't possible before, there won't be any effect
to existing builds, as param2 should always be '0'. The current
screwdriver mod also refuses to rotate and alter param2, so this is
safe to enable from now on.

Personally, since these are all *crafted* nodes to begin with, it
should be apparent that they can be rotated to begin with, but I can
see people may disagree from a simplicity perspective. It also may
affect param2 usage that other mods rely on, although I'm not aware
of any mods that do this.
