fixes #1989

move the plant to the bottom of its node properly, without affecting its scale.  See isue #1989

This should probably be removed when minetest_game has proper biomes.
If I hear "the whole map is just stone!" again after this, I am going to detonate.

If CMake is run and Doxygen is found, add a make target called "doc",
which builds API documention in doc/html. This target is not included
in the default "all" target, you have to explicitly run "make doc" to
generate the documentation.

If graphviz is installed, in particular, if the "dot" binary is found,
doxygen is configured to generate various kinds of diagrams. Note that
due to this, the first run of doxygen can take a while.
