Add options to delete and disable history for PowerRename

### Description of the new feature / enhancement

The history feature is rarely used. I hope there can be an option to turn off the history search form feature.

### Scenario when this would be used?

In daily use.

### Supporting information

Start by locating PowerRename's history search form, its settings entry points, and the code that stores history. Clarify whether the feature must both delete existing history and disable future history, then verify that the selected options change the form behavior as requested.
