More referrer possibilities

Tested local with

`gem 'search_sniffer',            '~> 1.0.0', :github => 'sofatutor/search_sniffer', :path => File.directory?('../search_sniffer') && '../search_sniffer'          # Referring search engine query string analyzer`

now referrer links possibile like:

`http://www.google.de`
`https://www.google.de`
`http://www.google.de/?gws_rd=ssl#q=mathematik`

This is needed for the FV4L Midroll Feature, witch will show up on SEO Traffic.
Weil ` CGI::parse(query_string)` sowas hier zurück gibt: `{ q= ['Foo Bar'] }` und `Rack::Utils.parse_query(query_string)` gibt das selbe zurück aber ohne Array, sprich join crasht.
