Viewmodel Shading Fix - NVSE

I'm on a roll with viewmodel fixes.

When Bethesda tried to mitigate floating point precision loss on viewmodel by shifting local playet position, they added a mechanism to shift lights to accommodate that position change.

As we know, that thing didn't go according to the plan. So you shouldn't be surprised if I tell you, that this light offset is also broken.

While lights get correctly shifted, the eye position is not (oddly enough it is calculated correctly in Lighting30Shaders, which are used only for decals). This means that you get correct diffuse lighting, but totally incorrect specular highlights, rendering (literally) weapon super dull and often dim. If you often wondered why weapons look flat - that's why.

The other issue is exact opposite - while eye pos was missing the offset, lights attached to the player are missing due to having the offset. This means that muzzle flashes, or any other light attached to viewmodel nodes (like in my Dynamic Pip-Boy Light), would not cast light at the player.

Both issues, fixed.

Also contains Pip-Boy Shading Fix (now hidden) - Pip-Boy would not receive any lighting if game's shadow system were inactive (disabled or replaced by mods such as NVR). If you have it installed, please uninstall it - failure to do so can result in crashes due to code changes.
