Components.WebView: Convert to using messages for JS method invocation

Browse source 
Use WebKitGTK UserMessage objects for invoking JS methods rather than
serialising to JS strings and running those. This is possibly slightly
less efficient, but removes the onus on serialising to and parsing from
JS and once switched over from message handlers to UserMessage objects
will be using a single uniform IPC interface for both.
