Support alternate message keys in footer

The existing MobileLicenseLink hook message allows the registration of only one
license URL. This gives more flexiblity to
applicable on projects like Wikidata where license differs depending on
namespace. It also allows another extension to substitute the message key
for something other than the default 'mobile-frontend-copyright'
