* Use image only when project has an image
So if there is no images, then projects can form a bit tigher and more
centered position in a square.
* Use same principle for all projects listing template
As per the review comment the listing of the projects would also be dependent on the existance of the image and creation of the space for it
* Add project_timeline to the project template
Project timeline is sometimes very important aspect of your project as
it shows that you have been working on it for some time. This adds the
feature to the template, but only uses it when it is defined.
* Add description of a new feature to README
* Apply suggestions from code review

This PR adds functionality for users to specify which `icon_pack` to use (`fas` or `fab`; see: https://fontawesome.com/how-to-use/on-the-web/setup/upgrading-from-version-4) in the `config.toml` file, so that users can use the solid icons as well as the brand icons.
```
[[params.social]]
url = "https://twitter.com/"
icon = "twitter" # icon name without the 'fa-'
icon_pack = "fab"
[[params.social]]
url = "https://facebook.com/"
icon = "facebook-f" # icon name without the 'fa-'
icon_pack = "fab"
[[params.social]]
url = "https://linkedin.com/"
icon = "linkedin-in" # icon name without the 'fa-'
icon_pack = "fab"
[[params.social]]
url = "mailto:youremail@email.com" # For a direct email link, use "mailto:test@example.org".
icon = "paper-plane" # icon name without the 'fa-'
icon_pack = "fas"
```
