Would be useful if cherry-picker messages were more prominent

As people have learned I am not always the most observant person in the world. My initial attempts to use cherry-picker were complicated by the fact that I paid attention to messages from git cherry-pick, not cherry-picker's own messages. It would be nice if the message sources were better distinguished, either by dimming the messages from git cherry-pick or by coloring the messages from cherry-picker.

If you think something like this would be useful, I could work on a PR. It seems that any desired changes would be straightforward, as current console output already uses click.echo().

Beginne damit, die Konsolenausgabe von cherry-picker zu finden, die click.echo() verwendet, und vergleiche dann ihre Meldungen mit der in der Issue beschriebenen Ausgabe von git cherry-pick. Als erledigt gilt die Aufgabe, wenn die Meldungen von cherry-picker sichtbar von den Meldungen von git cherry-pick unterscheidbar sind und die relevanten Ausgabepfade abgedeckt werden.
