Title: Allow to use a text logo when logo_url setting is set to an empty value

Added a conditional that now tests if the logo_url is empty. In case it is, the logoHTML function now returns a header tag with the site_title as its value, instead of returning an image tag that would only show the alt text in the browser.

Situation: SiteSetting.logo_url = ""
