As much as I enjoyed using Waterfox, the update to Firefox (and its
developer tools) is pretty nice. Since many add-ons now support this
new version of Firefox, I think it's now time to make the switch.
This commit:
- Moves aliases to .aliases.sh. Aliases can now be used with
both zsh and fish.
- Adds the ability to automatically create an upstream remote
with the hub function.
- Finalizes the fish prompt to be consistent with zsh.
