Added Drawable module, still have the comments to add and have to test if it works, but theoretically it should be good to go.

/* Abstract base class for objects that can be drawn to a render target.
*
* SFML::Drawable defines the attributes and operations that are common to all the drawable classes:
*
* - transformations (position, rotation, scale, local origin)
* - global overlay color
* - blending mode with background pixels
* - the ability to be drawn on either RenderWindow or RenderImage
*
* Please note that all these attributes are hardware accelerated, therefore they are extremely cheap to use
* (unlike older libraries that perform slow transformations on the CPU, such as rotation or scale).
*
* Usage example:
*
* # Here we'll use a SFML::Sprite to demonstrate the features of SFML::Drawable
* drawable = SFML::Sprite.new( ...whatever... )
*
* drawable.SetOrigin(10, 20) # set its origin to the local point (10, 20)
* drawable.SetPosition(100, 100) # set its position to (100, 100)
* drawable.SetRotation(45) # set its orientation to 45 degrees
* drawable.SetColor(sf::Color::Red) # set its global color to red
* drawable.SetBlendingMode(sf::Blend::Add) # set an additive blend mode
*
* window.draw( drawable ) # finally draw it (window is a SFML::RenderWindow)
*
* Deriving your own class from SFML::Drawable is possible, however you have to use the SFML::Renderer class instead of
* direct OpenGL calls, which is more limited. To create a derived drawable class, all you have to do is to override the virtual Render function.
*
* One of the main benefits of creating your own drawable class is that you can build hierarchies of drawable objects.
* Indeed, when you draw a drawable inside the Render function of another drawable, the former inherits the
* transformations and color of the latter and combines them with its own attributes. This way, you can apply global
* transformations/color to a set of drawables as if it was a single entity.
*
* Example:
*
* class MyDrawable
* include SFML::Drawable
* # ...
*
* def initialize
* @myTexture = SFML::Image.new( ...whatever... )
* @mySubSprite = SFML::Sprite.new( ...whatever... )
* end
*
* def render( target, renderer )
* # Low-level geometry rendering
* renderer.setTexture( @myTexture )
* renderer.begin( SFML::Renderer::QuadList )
* renderer.addVertex(...)
* renderer.addVertex(...)
* renderer.addVertex(...)
* renderer.addVertex(...)
* renderer.end()
*
* # High-level drawable rendering
* target.draw(@mySubSprite);
* end
* end
*
