model-combined-transparent was replaced by calling model-transparent causing the ALS
externel canopy effects to get lost. Call model-combined instead which restores these
effects.
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
Previously haze calculations were performed
in the main body of the ws30 shaders (inherited
from the ALS terrain shaders). This change creates
a common applyHaze function to consistently apply haze.
This is not ws30 specific, and could be used to replace the
haze calculations of all ALS shaders for improved consistency.
This brings a developer comment to the FlightGear-Qt.xlf files that will
hopefully draw the translators' attention on the fact that they should
put the *up-to-date* address of the "getstart" manual in their language
(use correct address + two occurrences of 'en' to change).
Added enabled tags to video-start and video-stop. These are set to true/false
by C++ code depending on whether we are encoding to video or not. [There
doesn't seem to be a way of doing this directly in xml - expressions are not
supported in menu items?]
