Make the front end more "pretty"

Make the frontend more "pretty".

Currently loading and adding models as well as loading and adding textures is a bit ugly but could be made nice quiet easily with some lines of code in the asset manager.

For reference, this was the old way in the front end to import a new texture and create a new mateiral from it:

    ///Creating a new material, currently a bit ugly
    {
        let render_inst = render.clone();
        let mut render_lck = render_inst.lock().expect("failed to hold renderer");
        //Create a second material
        //create new texture
        let new_texture = core::resources::texture::TextureBuilder::from_image(
            "/share/3DFiles/TextureLibary/Comix/Mariuhana.jpg",
            (*render_lck).get_device(),
            (*render_lck).get_queue(),
            settings.clone()
        ).build_with_name("new_texture");
        asset_manager.get_texture_manager().add_texture(new_texture);

        let (_ , normal, physical) = asset_manager.get_texture_manager().get_fallback_textures();

        let texture_in_manager = asset_manager.get_texture_manager().get_texture("new_texture");

        let mut new_material = core::resources::material::MaterialBuilder::new(
            Some(texture_in_manager),
            Some(normal),
            Some(physical),
            None,
            asset_manager.get_texture_manager().get_none()
        ).build(
            "new_material",
            "DefaultPipeline",
            (*render_lck).get_pipeline_manager(),
            (*render_lck).get_uniform_manager(),
            (*render_lck).get_device(),
            (*render_lck).get_queue(),
            settings.clone()
        );

        //add to the manager
        asset_manager.get_material_manager().add_material(new_material);
    }

now its like this:

    //Importing the texture
    let mut tex_builder = asset_manager.create_texture("/home/siebencorgie/Pictures/MyPictures/ben_mauro_01.jpg");
    tex_builder = tex_builder.with_flipped_v();
    asset_manager.add_texture_to_manager(tex_builder, "new_texture").expect("failed to add new_texture");
    //Creating a material and adding it to the manager internally 
           let (_ , normal, physical) = asset_manager.get_texture_manager().get_fallback_textures();
        let texture_in_manager = asset_manager.get_texture_manager().get_texture("new_texture");

        let new_material = core::resources::material::MaterialBuilder::new(
            Some(texture_in_manager),
            Some(normal),
            Some(physical),
            None,
            asset_manager.get_texture_manager().get_none()
        );

        asset_manager.add_material_to_manager(new_material, "new_material").expect("failed to add new_material");

Note that the example also involves to get some additional textures to create a full-blown material.
