Issue title: gh-pages project pages not working
 Issue body: It seems that the gh-pages link to service-specific modules isn't working.

This is working: 
http://www.brendanhay.nz/amazonka/

but this is not: 
http://www.brendanhay.nz/amazonka/Network-AWS-SWF.html

The Hackage pages are also fine:
https://hackage.haskell.org/package/amazonka-swf-0.3.4/docs/Network-AWS-SWF.html

Thanks for all the hard work!
