Title: Fixes for older zsh/coreutils

This removes the need to return from the main init by exiting modules that arnt compatible with older zsh versions.

Majority of functionality can be retained, aliases etc.

Also exit modules if the required tools arent installed so aliases dont get setup if not needed.

Also group-directories-first was added to coreutils6 so only alias ls to it if coreutils if new enough.
