Added feature to API to allow for limits on spawning altitude also. None of 

the included plants use this, it's mainly for the conifers mod.

The first of these, spawn_on_surfaces() is defined with quite a large number
of variables:
of variables. All of the variables below, if specified at all, must be
specified exactly in the order given here.
spawn_on_surfaces = function(sdelay, splant, sradius, schance, ssurface,
savoid, seed_diff, lightmin, lightmax, nneighbors,
ocount, facedir)
ocount, facedir, depthmax, altitudemin, altitudemax)
The first several of these are all required, and are from the last version of
the flowers mod, so this part of the API should be the same as before.

to the map. Defaults to 0.
depthmax: If a node spawns on top of a water source, the water must be at
most this deep. Defaults to 1 node.
altitudemin: Items must be at this altitude or higher to spawn at all.
Defaults to -31000.
altitudemax: But no higher than this altitude. Defaults to +31000.
