Add poplar tree

Poplars exist in two kinds: small and large trees. Both use the same
nodes, except for the sapling. Poplar leaves may drop one or the
other sapling.

Poplar trees require a humid environment, and water nearby.
Provided there is water, an occasional poplar will grow under less humid
conditions.
