Track file moves and globally replace without having to send a request each time

[Rainer Rillke]

Currently a script is used to add global replacement requests to the delinker-page.

Commons Delinker should track file moves and globally replace without having to send a request to the commands-page each time.

There should be a way (e.g. prefixing the move-reason with !R or similar) to prevent automated replacement.
