this includes the jump to conftrack, a custom-written configuration
library that'll hopefully be less annoying to deal with than conferer.
It's very much unstable & somewhat incomplete software for now, but
should hopefully reach a stable state soon (this deployment is thus
basically part of testing it).
It also means we can finally write camelCase in config keys without
having the config library fail on us!
