name default datacat_collector after title

This should make it a little more obvious in cases where people use multiply
targetted datacat resources:

   datacat { 'service::server':
     path => '/etc/service/server.cfg',
     template => 'service/server.cfg.erb',
   }

   datacat_fragment { 'something for server and client':
     target => [ 'service::server', 'service::client' ],
     data => { "my_amazing_setting" => "11" },
   }
