Some death screens and sounds

The following update includes some new death sound effects which is the "Howie scream" particularly as well as a death screen that informs the player that you have died and upon that you return back to the beginning of the level you started on. I even added in some new assets in one of the secret areas that lead to a trap for the player which is treasure to entice farther exploration.

Here below you will see some examples of what updates I have done which are most noteworthy.
