Content sponsorships now work without JS

Also, content with multiple sponsors will be identified, but the sponsors names will be hidden to avoid clashing. 
Folding straight into a count will not work with multiple tags with the same sponsor. 

Eg.. Article has the tags "cars" and "roadtrips". 
If both tags are sponsored by "CarCompanyX" then the count will yield a sponsor count of 2.  Collecting them first and then flattening it will yield a sponsor count of 1.
