Dungeons of Hazard - new name and some bugs are fixed

Hello everyone,

I have updated by game and renamed it by the way.

Here are the changes I made:

- player's  melee attack (fist attack) is now less powerfull
- fixed a graphics bug in the trap doors 
- fixed a graphics bug in the doors (doors werent always visible)
- reduced the volume of some sounds (saw blades, melee attack, zombie grunting)
- fixed a collision bug (by collision with a zombie, player somtime got pushed into a wall)

- AND I changed the name if my game from After Hazard to Dungeons of Hazard
