    Fix retrieving snippets when using the web-interface.
    Modifications for remote hit happens at two places now:
    - remote: The server adds hit:beagle:NetworkNode=name_of_this_service
    - local: The NetworkService queryable modifies hit:Source to point to itself so that future snippet requests are directed to it instead of whatever remote set hit:Source to.
