V0.4a - Players requested

Some of you asked me to modify the following "annoying" mechanics:
- Once you trigger the child it does NOT shake both players screen anymore. The child's scream is not hearable for players too far from it.
- Once you trigger the Psycho it does NOT shake both players screen anymore. The scream is not hearable for players too far from it.

New:
- Camera is slightly shakes once you get damage taken

Fix:
- Once a player died, the game did not finish for the other player
