Add "Change tracker URL" to the context menu in the tracker filter widget

Suggestion

Add "Change tracker URL" to the context menu in the tracker filter widget. This will quickly change the current tracker address for all torrents.
Either "Change tracker domain", as the URLs may be different and mass change will be problematic.
Similar to "Edit tracker URL" for a single tracker.

Now you need to use third-party tools to do this, for example https://github.com/rumanzo/qbtchangetracker
