Add styling to differentiate each steps of the main script more easily (

#55)

* Add styling to differentiate each 'update' steps more easily

This PR aims to add some basic styling to differentiate each `update` steps (regular packages, AUR packages, Flatpak packages) more easily.
This makes the script more "transparent" about what it does and will also be useful for eventual debugging.

* Add style for orphan/unused removal as well

* Add correct spacing

* Styling

* Add style for pacnew processing
