Description:
The quest is marked complete when any capacitor is held
The capacitors used to craft have to be empty

Fixed the quest, now it takes a Creative Capacitor with either the {Energy: 25000000} tag, or the {Active: 0 as byte, Energy: 25000000} tag. It's weird that it also accepted other TE Flux Capacitors, becuase they're technically different items (their damage values are different, which should have been enough for BQ to recognize them as different items, see for example Thermal machines, they all have ID 4438, but are differentiated by damage value). Anyways, I had to do some NBT trickery, but it works now!

Additionally, the Flux Capacitors that the recipe takes having to be empty - again, Thermal is doing something in the background. I specified any NBT (which is done by specifying no NBT in ZenScript), but for some reason it only accepts ones with {Energy: 0}, even though "{Energy: 0}" doesn't appear anyhwere in the script. Instead I made it clear in the quest book that it can only use empty input Flux Capacitors.
