std::string?

I agree that we should be sending strings instead of string16s over IPC but that
isn't the convention in service_worker_messages.h.  I went with the convention.

+
 //---------------------------------------------------------------------------
 // Messages sent from the browser to the child process.
 //
 // NOTE: All ServiceWorkerMsg messages not sent via EmbeddedWorker must have
 // a thread_id as their first field so that ServiceWorkerMessageFilter can
 // extract it and dispatch the message to the correct ServiceWorkerDispatcher
 // on the correct thread.
 
 // Informs the child process that the given provider gets associated or
 // disassociated with the registration.
