render: Bypass texture rendering when a model uses the null texture.
* data/shaders/default-fragment.glsl (use_texture): New uniform.
(main): Skip texture rendering when 'use_texture' is false.
* sly/render/model.scm (draw-model): Set 'use_texture' uniform before
rendering.
* sly/render/shader.scm (load-default-shader): Register 'use_texture'
uniform.
