the output 9 but that would make it all too quick and easy (especially for griefers) to create lots
of snowblocks (and then use them to water-grief by melting the snow blocks).

--=================
--======================================
LazyJ's Fork of Splizard's "Snow" Mod
by LazyJ
version: Umpteen and 7/5ths something or another.
2014_04_12
--======================================
--=================
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
THE LIST OF CHANGES I'VE MADE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Falling snow would destroy nodes it deposited snow on. I figured out that if
I switched the 'snow.place' with 'minetest.place_node' and increased the
y position by 2, then the nodes were nolonger destroyed and the snow
would start to pile up.
~~~~~~
TODO
~~~~~~
* Add code to prevent snowfall from depositing snow on or
near torches and lava.
* Add code to prevent snowfall from depositing snow on
'walkable = false' defined nodes.

--======================================
LazyJ's Fork of Splizard's "Snow" Mod
by LazyJ
version: Umpteen and 7/5ths something or another.
2014_04_12
--======================================
--=================
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
THE LIST OF CHANGES I'VE MADE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The HUD message that displayed when a player sat on the sled would not go away after the player
got off the sled. I spent hours on trial-and-error while reading the lua_api.txt and scrounging
the Internet for a needle-in-the-haystack solution as to why the hud_remove wasn't working.
Turns out Splizard's code was mostly correct, just not assembled in the right order.
The key to the solution was found in the code of leetelate's scuba mod:
http://forum.minetest.net/viewtopic.php?id=7175
* Changed the wording of the HUD message for clarity.
~~~~~~
TODO
~~~~~~
* Figure out why the player avatars remain in a seated position, even after getting off the sled,
if they flew while on the sled. 'default.player_set_animation', where is a better explanation
for this and what are it's available options?
* Go through, clean-up my notes and get them better sorted. Some are in the code, some are
scattered in my note-taking program. This "Oh, I'll just make a little tweak here and a
little tweak there" project has evolved into something much bigger and more complex
than I originally planned. :p ~ LazyJ
* find out why the sled disappears after rightclicking it ~ HybridDog

A note about default torches, melting, and "buildable_to = true" in default snow.
On servers where buckets are disabled, snow and ice stuff is used to set water for crops and
water stuff like fountains, pools, ponds, ect.. It is a common practice to set a default torch on
the snow placed where the players want water to be.
If you place a default torch *on* default snow to melt it, instead of melting the snow is
*replaced* by the torch. Using "buildable_to = false" would fix this but then the snow would no
longer pile-up in layers; the snow would stack like thin shelves in a vertical column.
I tinkered with the default torch's code (see below) to check for snow at the position and one
node above (layered snow logs as the next y position above) but default snow's
"buildable_to = true" always happened first. An interesting exercise to better learn how Minetest
works, but otherwise not worth it. If you set a regular torch near snow, the snow will melt
and disappear leaving you with nearly the same end result anyway. I say "nearly the same"
because if you set a default torch on layered snow, the torch will replace the snow and be
lit on the ground. If you were able to set a default torch *on* layered snow, the snow would
melt and the torch would become a dropped item.

This section of code that makes blocks compatible with MoreBlocks' circular saw.
I've added circular saw compatible code for default snowblocks and ice. :D
A big thanks to Calinou and ShadowNinja for making this possible.
Because StairsPlus creates partial blocks, it didn't seem quite right that the
smallest microblocks would produce a full-sized water_source node when melted.
So I toned them down a bit by changing their melt to a temporary,
2-second water_source. See "melts" in abms.lua file for the various intensities.
___...::: ATTENTION MINETEST SERVER OPERATORS :::...___
You may or may not have noticed in your server logs that MoreBlocks stairs/slabs/
panels/microblocks are not recorded as to when, who, what, and where. This is
important information when trying to determine if a player who dug these blocks
is the owner (the player who placed the block) or is a griefer stealing the block.
There is an option that will log when these blocks are placed but it comes at the
cost of losing the auto-rotation of those blocks when placed. They can still be
rotated with a screwdriver but if screwdrivers are disabled on your server your
players won't be able to position MoreBlocks, saw-made blocks.
To enable logging the placement of these blocks, un-comment these lines:
--on_place = minetest.item_place
There is one in each of the "stairsplus.register_all" sections.

Below, in the "groups" line there is a "melts" category. Back in the ABMs lua file, melting
code, melts=1 will produce a water_source when the full-sized snow/ice block is melted making
a big, watery mess. melts=2 will produce a water_source only for a moment, then it changes back
to water_flowing and then dries-up and disappears. I gave these stairs/slabs/panels/microblocks
a melts value of 2 instead of 1 because they are not full blocks.
