Add the new/revised logo to the site

[jaylenw]

Problem

There are locations where we can post our new logo on the site.

Solution

After the development of a new/revised logo, let's place the logo on the locations that the current site template expects to be.

Currently, the logo will be present on the top left in the nav bar and in the footer. We can discuss more about this to see if we actually like the logo to be in these locations.
