**When merged this pull request will:**
- Changed hardcoded 0.5 NVG fog modifier for players in "air" type vehicle to CBA option (0.1 to 1.0 range).
- Added CBA options for fog modifier (0.1 to 1.0 ranges) for tank crew, car crew, static weapons and when using NV-capable binoculars.
- These fog modifiers are only applied when in gunner view of a NV-capable seat/turret, otherwise players still use their own NVGs.
- NV-capable binoculars work from FFV seats with binocular modifier.
- Fixed nvg overlay not applying when using FFV seats/ADS from FFV.
- Added ADS blur when using non-NV capable static weapons, technical turrets with NV goggles.

Known issues:
- When coming  out of binos, noticable flash at the corners of the screen before the NVG overlay is applied. Issue present in current ACE release. Wasn't able to resolve.
- UAV cameras are affected by ACE_player's nightvision status. If ACE_player has nightvision on, the NVG effects are overlaid on the UAV camera. Issue present in current ACE release.
- Unable to reliably detect when player controlled UAV is changing vision modes to account for UAVs. Potential bug with CBA Visionmode player EH. The EH doesn't trigger when changing from normal to night vision in when remote controlling drone. Raised issue on CBA github, CBATeam/CBA_A3#1004
