Update minetestforfun_game with minetest_game

- I hope there is no problem. I see a lot of new stuff in the vanilla
  game. I keep a backup on another computer to restore the state of the
  repository if there is a problem.

+Leafdecay
+---------
+To enable leaf decay for a node, add it to the "leafdecay" group.
+
+The rating of the group determines how far from a node in the group "tree"
+the node can be without decaying.
+
+If param2 of the node is ~= 0, the node will always be preserved. Thus, if
+the player places a node of that kind, you will want to set param2=1 or so.
+
+The function default.after_place_leaves can be set as after_place_node of a node
+to set param2 to 1 if the player places the node (should not be used for nodes
+that use param2 otherwise (e.g. facedir)).
+
+If the node is in the leafdecay_drop group then it will always be dropped as an
+item.
+
+Dyes
+----
+To make recipes that will work with any dye ever made by anybody, define
+them based on groups. You can select any group of groups, based on your need for
+amount of colors.
+
+#Color groups
+-------------
+Base color groups:
+- basecolor_white
+- basecolor_grey
+- basecolor_black
+- basecolor_red
+- basecolor_yellow
+- basecolor_green
+- basecolor_cyan
+- basecolor_blue
+- basecolor_magenta
+
+Extended color groups (* = equal to a base color):
+* excolor_white
+- excolor_lightgrey
+* excolor_grey
+- excolor_darkgrey
+* excolor_black
+* excolor_red
+- excolor_orange
+* excolor_yellow
+- excolor_lime
+* excolor_green
+- excolor_aqua
+* excolor_cyan
+- excolor_sky_blue
+* excolor_blue
+- excolor_violet
+* excolor_magenta
+- excolor_red_violet
+
+The whole unifieddyes palette as groups:
+- unicolor_<excolor>
+For the following, no white/grey/black is allowed:
+- unicolor_medium_<excolor>
+- unicolor_dark_<excolor>
+- unicolor_light_<excolor>
+- unicolor_<excolor>_s50
+- unicolor_medium_<excolor>_s50
+- unicolor_dark_<excolor>_s50

+Example of one shapeless recipe using a color group:
+minetest.register_craft({
+	type = "shapeless",
+	output = '<mod>:item_yellow',
+	recipe = {'<mod>:item_no_color', 'group:basecolor_yellow'},
+})

+dye.excolors
