Added a new setup proposal, builder is no more derived from shell script (where edit=glibc rebuild), but is composed from a nix attribute set with strings and dependencies - so if you add a function, old expressions ignore it; collateral damage are packages in this style: Fastest Fourier Transform in the West, Audacity sound editor, Falling Sand game. Also added string equality that ignores dependencies to lib. Note that hasSuffixHack is now the more predictable version, but hasSuffix is left to remind us to fix the bug.
