Adds auto-expand to some of my aliases

Heavily inspired by this: https://dev.to/frost/fish-style-abbreviations-in-zsh-40aa

When space is pushed, zsh will try to expand any aliases that I have put
in the array in this file.

It is currently quite basic, only looking at the first word on the
command line.
