Rewrite archiver project
* Rewrite archiver.rkt to manage the stages order * Rewrite archiver-gui.rkt: * Remembers the previous incomplete queue items * Pretty graphics for icons and progress bars * Segmented progress bars to indicate different stages * Fix archiver-cli.rkt to use new stages * Switch to req -d, so it doesn't auto-install gui libs
