Site Title

I'd find it greatly helpful for a way to set the site title through the GLPI configuration rather than editing HTML templates. 

Example, the landing page is Standard Interface - GLPI where Standard Interface is a variable passed to the rendering of the html template, but  GLPI is hard coded into the template. I'd be a major benefit to larger users if they could replace GLPI in the title with COMPANY_NAME Support or what ever they'd like.

As stated earlier the only way to accomplish this is via editing of templates/layout/parts/head.html.twig which isn't a great option.
