New: CPU Usage Statistic (#65)

* Use libmacchina v0.2.2, and include CPU usage

- This PR brings the latest that libmacchina has to offer, starting from
  a new feature, which is quite nice to have, and that is CPU
  usage/load. Did I hear you say "bar"?

Yes you can use bars to visualize your processor's load!

- It also fixes a slight little copy & paste mistake, which I'm happy
  didn't cause any trouble.

- Another neat little feature is the --no-title flag, so if you don't
  like the idea of box titles, you're in luck, you no longer have to use
  --box-title "" to achieve what --no-title's purpose.

* Change up the order of readouts

- This was mostly done to accomodate for CPU usage, so that every
  readout that can display a bar, can have a nice aesthetic because all
  the bars are stacked on top of each other. And another reason, is because
  the order of readouts before this change, did not make much sense, at least to me.

* Update preview images and Changelog.txt

* Update the program's about/description

 _Macchina_ comes with a very special flag, allowing you to know why certain elements, for example, your operating system information might not be appearing. It can differentiate between errors, and warnings, and its comprehensive output should help you understand where the issue is coming from.
 
 To use this feature, run `macchina --doctor`
