Version 0.4 uploaded

In this version, there are effects. Lights can be triggered by pressing "L" and flickered by pressing "F". Of course, later these won't be triggered by keypress but by events. If you press the "C" key, there is a sinking feeling effect with a bass drop. Lastly, the character now has footstep sounds and when walking or running bobbs head. If you hit left shift while walking, you begin to run.
