Use shaders to disable shadows from some models

[hemebond]

Raton has brought to my attention, and MrC has confirmed it in the below example, that shaders can be used to disable shadows being cast from certain textures and models by using the dpnoshadow keyword. An example from MrC:

progs/flame.mdl_0
{
	dpnoshadow
	{
		map progs/flame.mdl_0
		rgbgen lightingDiffuse
	}
}

progs/flame2.mdl_0
{
	dpnoshadow
	{
		map progs/flame2.mdl_0
		rgbgen lightingDiffuse
	}
}

progs/lavaball.mdl_0
{
	dpnoshadow
	{
		map progs/lavaball.mdl_0
		rgbgen lightingDiffuse
	}
}
