Add High-Visibility Iron Sights / Tritium Night Sights for Weapons

The idea is as simple as it gets: mechanical sights are practically invisible in the dark, so why not add tritium glowing front sights? There are people who prefer mechanical sights to optical or collimator ones, and for them this will be a nice bonus, and in general, the implementation of such a detail as a separate module is cool. Selecting the type of front sight and the color of the dot/line itself.
