Allow the snow level of the landmass shader to be set from the property system, and expose it in the rendering dialog. Could be used in future to set the snow level based on the current weather.

fix shader bugs on ATI hardware
...
The main problem was using gl_FrontMaterial.ambient with a color mode
of AMBIENT_AND_DIFFUSE i.e., the fixed function path would take both the
ambient colors from the vertex color value. Also, some vertex shaders
were not writing gl_FrontColor even though the fragment shader was
accessing gl_Color.

From Lauri Peltonen (Zan):
...
These two patches allow use of external shaders as the tree and 3d cloud
shaders. The shaders are Shaders/3dcloud.{frag|vert} and
Shaders/tree.{frag|vert}. If the shader files are not found, the
original shaders included in the source are used.
This makes testing modifications to the shaders easier and faster. End
users should see no difference when using this.
