Massively buff lux absorption of reinforced glass.

[Byrnorthil]

(from commit message): "A lux-absorb value of 20 provides 20/64 absorption, or just over 31%. This value is likely much lower than WintersKnight intended, and is in fact less than half as effective as the 83% absorption it would have due to its cracky value if the line was omitted. I've given it the metallic group (100% absorption) as that seems to be the intention."

Radiation logic is here; lines 72-87 are most important in this case. In the future, I would suggest more thorough research, rather than making up a number which feels right. Testing of the rad blocking in-game would also reveal mistakes like this.

...this is all assuming you actually want the glass to be good at blocking rad. If not, hats off for the bamboozlement.
