chuck dead crafting reciepes

* bushes ground content

minetest default game treats all bush parts as ground
content, so we do that here too. The baskets however are
player made and placed, so they aren't ground content

* cavestuff ground content

Pebbles are given to mapgen as decorations, so they have
been left as ground content.
The stalactites are not ground content

* user 'placed' nodes -> not ground content

* ground content revision
