Issues with processing files

[AidanTilgner]

The files to process check needs to happen before the private check:

        for file in self.walker.walk_files():
            if len(new_files) >= self.file_limit:
                return
            if not self.file_is_type_to_process(file):
                continue
            if self.file_is_private(file):
                continue
            new_files.append(file)

There should also be updated support for privacy.
