rtx: add include support for materials

Browse Source 
use it like this:
```materials.mat
{
	"include" "other.mat"
	"include" "another.mat"
	// ...
}

// continue with regular material definitions
```

```other.mat
{
	// can also nest includes (up to 4)
	"include" "yetanother.mat"
}

// continue with definitions as usual

{
	// may also have includes later too
	"include" "whatever.mat"
}

// ...
```

etc
