Option for Unix End of Line format

[twiz-git]

Currently it uses Windows EoL (CR+LF), for obvious reasons, but many Windows text editors (including Notepad and Wordpad) as well as Checksum tools handle the Unix EoL (LF) without issue. This would be helpful for people like me who copy/back up to a Linux system whos *sum commands do not handle the Windows EoL properly.
