Previously the water shader was separate and executed on a
different mesh.
This adds the water shader as a separate fragment function
(ws30-water.frag) and uses a material parameter passed in
as a Uniform to use it in preference to the usual texel
lookup.
Performance testing found a slight performance improvement
from having a single mesh, but a slight performance impact
from the extra fragment shader complexity.

Add Milky Way onto the night sky
The texture array used by WS30 requires that all
component textures be the same size and format.
This commit adds an alpha channel to those
png file used as primary textures in materials.xml
files which did not have one.
Materials changes version 2 - Iceland and California
1. Keep regional definitions for the new default airport BIKF, and Iceland. Uses
new grass colours texture airport-grass-summer3.png with custom autumn effect i
n alpha channel, and bare volcanic bare ground layer - to produce patchy grass a
nd blend in with surrounding landclasses. 3d grass overlays have height modulati
on turned on so grass patches are followed. Actual grass cover and colour at BIK
F varies a lot even for the same month in different years going by photos, needs
autumn effect to depict the range properly. The grass near the terminal areas s
eems to receive a more water while the rest is often quite bare in photos - the
current patchy-ness is a compromise. The texture for low settings is still autum
n-grass-summer2.png.
2. Keep regional definitions for KSFO and California. Switches to grass effect s
o 3d grass is enabled. Grass layer and patchy bare ground layer format with heig
ht modulation for 3d grass. Currently tuned to hints of dry green grass similar
to the old version.
