v0.405 Fix for issue that was affecting difficulty and other fixes.

Version v0.405 is now live.

[h3]Changelog:[/h3]

Fixed new bug that caused player to receive less damage on normal difficulty and more damage on easy difficulty. Basically difficulty of easy and normal was accidently swapped in previous update.
Dog will now bark while running if player is far from the dog, to make it easier to find the dog if player has lost it.
Fixed bug that caused shell ejection on hunting rifle, when player switched to different weapon and then switched back to hunting rifle.
Fixed bug that could cause animal AI to not work properly when animal is spawned near angry ghost.
Fixed bug that could cause angry ghost icon to be visible after game load.
Fixed issue that could cause bug where sniper scope stays enabled, when player is switched to shotgun.
Other small changes and improvements.
