Title attribute of institutional logo is not skinnable

The `title` attribute of the institutional logo on the landing page is not skinnable. Rather it contains the generic "Open Academic Environment," and this is what users see on mouseover or screen readers speak. It might be better to make it skinnable per tenant.
