Patch Notes:

- Minor bug fixes.

- Added interface messages for hiding.

- Added footstep sounds.

- Adjusted noise system to be more realistic and difficult.

- Adjusted Monster spawn rate.

- Added crouched sprite when hiding next to a corpse.

*I am aware there is a bug with the steps and noise systems, where the steps are not always registering.  As well as a sprite layer bug, where the objects in the room aren't layering properly.
