Subject: [PATCH] Add debug command to spawn mcl_farming plant nodes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds the debug command “/generate_farming_plant_rows”. The
command generates rows of plants and stems per plant type near a player.
A farming soil or glass node is placed below each node, so players can
find and examine possible gaps between a plant node and a node below.
