It's now in game_api.txt

The left-handed recipes for axes were using default:stick instead of
the group:stick used by all other tool recipes.

This adds protection for furnaces (when the area is protected, so it the
furnace).
Also made the codes a bit shorter..

Also, move "waving = 1" property for grasses/shrubs over to default/nodes.lua
and put all instances of this property right under the drawtype, since they
are directly related and depend on the above.

<PilzAdam> why dont you include sam II in there?

hat layer, when the area for the cape (a 8x12 set of pixels) which is to
the right of the arm texture, is given a non-alpha or semi-alpha pixel,
it will display ingame, similar to the hat layer on the player's head.
