Description

With the changes from IO-629 I'm getting an AccessDeniedException when trying to recursively delete a directory with read-only files, e.g. a .git repository. Before this change the directory was successfully deleted. It is due to the difference between File.delete() and Files.delete() (see https://stackoverflow.com/a/12234217/3375325).
I think an option should be introduced to make the previous behavior available again with an overloaded method like PathUtils.delete(Path path, boolean force).
