Alexander Schmolck 8d4b6766e2 Convert short nix options to long ones 
e.g. nix-env -e subversion => nix-env --uninstall subversion

The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.

The change was made with the following script:

and sanity checked visually.

Upgrading Nix

Multi-user Nix users on macOS can upgrade Nix by running: sudo -i sh -c 'nix-channel --update && nix-env --install --attr nixpkgs.nix && launchctl remove org.nixos.nix-daemon && launchctl load /Library/LaunchDaemons/org.nixos.nix-daemon.plist'

Single-user installations of Nix should run this: nix-channel --update; nix-env --install --attr nixpkgs.nix nixpkgs.cacert

Multi-user Nix users on Linux should run this with sudo: nix-channel --update; nix-env --install --attr nixpkgs.nix nixpkgs.cacert; systemctl daemon-reload; systemctl restart nix-daemon
