v0.2.0-release
Source code:
- Scene.java moved to radiant/assets/scene/
- Light.java now called PointLight.java
- Unit test for Path comparison in hashmaps added

Features:
- Directional lighting model added
- Directional lights can be specified in the scene file
- Material file can be specified in the scene file
- Tiling of all the textures is specified in the scene file
- Diffuse/Normal/Specular maps can be specified in the material file
- Diffuse map sampling can be specified in the material file
- Material hardness can be specified in code
- BaseGame/loadWindow has parameters to set the title and size of the window
- Paths can be compared properly due to added hashCode/equals method
- Matrix4f has an added transform method to allow in-code transformation of a Vector3f

Components:
- DirectionalLight component for directional lighting

Refactoring:
- Renderer has a create method for initialisation work
- Renderer now only renders the scene that is set to render. This prevents passing the scene to every method.
- Light component is now known as PointLight
- Lights now have a Vector3 for attenuation instead of separate variables (x = constant, y = linear, z = quadratic)

Fixes:
- Orthographic camera projection now gives back a correct matrix
- Changed ArrayLists in Mesh to List to allow future changes in the implementation
