Demo Update V2

More fixes based on players' input. Changelog:

• Shotgun and Hunting Rifle textures have been reworked. A cosmetic scope has been added to the hunting rifle model. They will probably be reworked again. - Added a First Aid Kit in the demo, as the third reward of the shooting range. - Tutorial boat cutscene can now skipped by pressing Main Action button for 3 seconds. - The screen effect when player is on low health is now less annoying. - A zombie behind a curtain would stay quiet if triggered and if the player would exit and re-enter the room. Fixed. - First ‘tutorial’ zombie in the cottage will now have a bit less of health than the rest.

Work on full release advances steadily.
