New Nginx config

Before we used to have everthing in one single default file, both in sites-enabled and sites-available folders. Now for each app/service we have a separate file created in the folder sites-available, which we reference through a symbolic link in the sites-enabled folder, here's two screenshots of how it currently looks:

home is the 'main page', there we can redirect to all the other services.

Given the case that we don't need a service anymore we can simply delete the symbolic link in sites-enabled.
