Make links in Echo's notification footer blue on hover

Links on the notification footer, "View edit" / "View changes", needs
to be blue instead of grey to be consistent with the Mediawiki interface.
The link turns blue upon hovering, just the way it is currently set
for other links on notifications like the page title.
