Changes to the TextureLoader's loadTexture method. Now it takes an InputStream instead of a path. This allows for loading from within a jar file. Started to move over the tests to the correct project.
Moved resource folder inside src package. This allows for InputStream loading of the assets through the engine's TextureLoader. Had to change how the images was read from storage in their paths and making a InputStream through their classLoader...

Started to move tests here.
