Subscriptions were effected by changes made to
homepage.
Remove defer from travel-advice.js script

Clicking on a country link directly after
filtering will not work. This was because the
change event was capturing it incorrectly.

updates them and adds new ones for the revised
HTMl.
Add phrasing to countries counter

Also adds tablet-down styles.
Add mixin & make email link external
Correct subscription links CSS
Fixes for JS & CSS issues
