Add keys

* fixed wall detection when looking round, (slight performance cost).
* fixed variable names using retarded wacky localized strings as variable names.

Tweaked wall avoidance mode: will no longer avoid walls if aimed down sights, unless for friendly

Fix for the fix which in turn was a fix for another fix

Update meta, mod .cpp and version
