Some tweaks to the notifications overlay
1. Instead of resorting, just reversing notifications array
2. Smaller font for notification footer, per Vibha
3. Making sure loading spinner is actually visible when active
4. Hiding primary link - this isn't supposed to be visible, but
   only used for constructing the psuedo-link for the entire
   notification div (to be implemented later)
