First attempt at a mod.

This mod was made to be fairly realistic.

This mod adds a second rank to sniper perk. If taken this mode will do a couple of things.

1) It will allow you to hold your breath fro limited amount of time thereby eliminating all gun sway. However you this will only be available while crouched and not in combat. As soon as you stop crouching tor an enemy begins combat with you your gun will begin to sway. Also the hold breath effect starts as soon as you start aiming and will only last for a limited amount of time. The amount of time it lasts will be effected by your weapons skill. Max amount of time will be 10 seconds if gun skill is at 100 min amount of time will be 0 if your gun skill drops to zero.

2) While crouching you will also gain a bonus to chameleon again only while crouching and not in combat. The bonus is directly related to sneak skill. Whatever your current sneak skill is the bonus you will get to chameleon. I added this to allow the player to more easily get into a good sniping position.

This perk is designed for a player to snipe and avoid being detected because when combat is entered all effects are lost.

Couple of other notes:
1) This perk will work with any gun that could have a scope even if does not currently have one equipped.
2) The chameleon bonus should maintain any chameleon bonus the player already has or gains while the effect if active. Also any negative effect to sneak will be reflected immediately to your chameleon bonus. So if your sneak skill drops fro any reason while effect is active your chameleon bonus will also drop. However the chameleon skill can only drop to the value you had before crouching.
