Make Radiation Collectors harder to upkeep and less productive

- Renamed drainratio to drain_ratio. Mostly a type case thing, also forced me to modify the admin verb debug code
- Radiation collectors now drain five times as fast. Still more practical than the AME, but every now and then someone will have to haul their lazy fucking ass to the Engine to refill the plasma tanks. If you want constant power, use the Solars
- Radiation collectors produce TEN times less power. A fully set Singularity Engine used to produce 3 million W, will now produce 300 000 W.  Supermatter Engine goes from 30 million W to 3 million W. Grid power weight is usually 25 000 W, so it sure as hell should be enough to power everything and top the SMES cells. Mathematically, that's 50 000 W per capped rad collector now

This effectively means three things :

- Engineers now have to check five times as often on the radiation collectors. Since those currently drain in a ridiculously long time, this doesn't really ruin everything
- You'll now have to try really hard to make electric shocks lethal if the Engine is wired to the grid. The Supermatter Engine should still output enough and the Singularity Engine might yield a crit, but no more
instant kills unless someone goes overboard with the rad collectors or engines stacking
- Scrubbing the plasma tanks, then cooling the plasma canister before using it is a pretty smart way to make tanks last longer and produce more. ATMOSPHERICS!

This is a pure value tweak, but one I feel is important. I also feel like the Singularity should output more radiation and the shard less, but that's something to be seen later on
If you're going to edit this, do it right: should be a formula (probably log function with floor), should support powerglubs, etc
