bin/pkg: Automatically symlink bin/*
Now I just need to wait some time and then I can make ~/bin point to packages/.collected/bin
implement package conflicts
bin/pkg: pkg_remove: Also remove symlinks from other places (~/.foo and such)
bin/pkg: Dependencies fuer Systemzeugs (binaries / perllibs / debianpakete ...)
bin/pkg: pkg_update: Remove symlinks that break due to the update
bin/pkg: Add 'triggers' (a package provides it's own crontab/zsh config etc, it is no longer in the package cron/zsh)
bin/pkg: pkg_remove: Check reverse dependencies
