Added missing docs on GUI properties and materials

No description provided.

I get confused by these documentations. Take this as an example:

go.property("mybigfont", resource.font("/assets/mybig.font"))

function init(self)
  local current_font = go.get("#gui", "bigfont")
  go.set("#gui", "bigfont", self.mybigfont)
end

The property declared is mybigfont, but in init it gets and sets a property bigfont, and refers to a self.mybigfont variable which is not mentioned. Is bigfont a built in property? I don't see it listed in the Properties page.

Also, should the property be declared under the gui script of #gui component? Is init function under another component script?

I've clarified the documentation a bit. The code should be run from a .script component. It makes use of resource properties to define a new resource to set. But in the case of a texture it could just as well be created at runtime using resource.create_atlas(). I've also added images which should hopefully explain it a bit better.
