Sorry about taking so long to reply. Nothing is wrong with it, I was more curious than anything. I also agree that SFML is a more important use of your development time.

General discussions / What happened to the Thor extension library?

I'm assuming RL got in the way, but I haven't seen a confirmation on that. Thor was a pretty useful extension even though I haven't really utilized it, yet. If I can, I will look into what it would take to update it. Also, if there is a newer alternative that is out there, it would be great to know about.

Graphics / Re: window.draw(*gameobject->getSprite()) texture is white, why?

I think the problem is your GameObject::setTexture method. You are passing the sf::Texture by value which means that particular instance will be destroyed as soon as that method returns.  You need to pass a reference or pointer and keep that reference or pointer alive somewhere else.

So a quick example:

In GameObject.h

// Rest of Game Object Declaration
void setTexture(const sf::Texture & gameobject_texture);
// Rest of Game Object Declaration

In GameObject.cpp

// Rest of Game Object Definition
// Basically the same as before
void GameObject::setTexture(const sf::Texture & gameobject_texture) {
    sprite.setTexture(gameobject_texture);
}
// Rest of Game Object Definition

In file where you set the texture:

// Rest of Code
sf::Texture texture; // IMPORTANT: Make sure texture outlives the GameObject
// Initialize the texture somehow
GameObject::GameObject* gameobject = GameObject::getGameObject("player_gameobject");
gameobject->setTexture(texture);
// Rest of Code

-- OR --

If you have C++11 or better compatibility (At least I think this should work)

// Rest of Code
std::shared_ptr<sf::Texture> texture = std::make_shared(new Texture()); // Now you can store the pointer somewhere else
// Initialize the texture somehow
GameObject::GameObject* gameobject = GameObject::getGameObject("player_gameobject");
gameobject->setTexture(*texture);
// Rest of Code

You could also use

std::unique_ptr<sf::Texture>

which enforces stricter ownership rules.
