Add the current user filter to every view using flag filters. Previously this was implied with all filters, now it is optional to increase the flexibility of flag.

For some reason Flag began providing a Node: Node ID argument in the 5.x port. Because this argument should be handled by Views' own node.inc file, update existing arguments to use that one instead.
