[PATCH] Wrong water colors on some maps

[elexis]

Some maps had light blue water in alpha 20 but have dark green water in alpha 21. This is very visible when water reflections are disabled. But even when they are enabled, the tendency is still towards green. This looks nice for many maps, but not suited for some.

Affected maps:

• Random:
  • Latium: dark green
  • Guadalic River: gray
  • Lorraine Plain: dark gray4
  • Northern Lights: grey water, refractions seem too strong in both svn and a20)
  • Pyrannean Sierra: dark blue. Also #4287: The waves were very clearly seen in a20, now one can't notice any surface features at all after disabling shadows on water
• Skirmish: None seem affected
• Scenario:
  • Siwa Oasis: too saturated water color in both releases and #4287

Should probably be fixed with setWaterColor, setWaterTint from environment.js for the random maps.
