Add styles to global.scss to make Magnolia & Jive consistent with Developer

- also remove the “http:” from static url’s to avoid issues with
“https:”
The only issue was http links on https sites, same stuff you had on JBoss Developer. So, I asked Cheyenne to use no-protocol URLs. Nevertheless, as far as I remember your 'cdn' handler will transform the URL to the same form so we can just change those URLs to use cdn.
There are no other issues with it, right ?
