Beta 3. Not a lot of really noticeable changes, just more polishing.

- Made Rifle scope shader toggleable, and tweaked its visuals a bit.
- Various adjustments to vector math (using portal-aware functions).
- Adjusted the penetration mechanics of the Quadshot, should be able to better go through multiple targets now.
- Fixed incorrect state jump after zoomed rifle altfire.
- Reduced the range of the Detector (2048 → 512), it was too massive.
- [flak_m] Fixed the issue where some looping weapon sounds would get stuck if the player died or dropped the weapon.
- Corrected Gun Lore description of Flamethrower altfire.
