Don't let the urban shader and the landmass shader fight over the city type terrain and restrict the landmass shader to only below a quality of 3.5

Bring the old urban shader (qualiti level=3.5) back to life on my video hardware by restricting the number of varying variables to a maximum of seven.

Disable self shadowing for now to gain some fps on older GPU. Should be configurable in the future

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.

more ATI fixes for crops and landmass shaders
...
Same problem with material state, except this time with the diffuse component.

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.

Till Busch - effects, shaders and textures for crop and water effects
...
Incorporated changes to effects file syntax. Changed Till's landmass
to mix in the base terrain texture. Some shader cleanup.
Also, add a GUI control for enabling shaders.
