This patch permits to specify a end of options marker,
I choosed the GNU usual '--'

patch by: lazy.et <lazyet users sourceforge net>

* ed2k_hash/cl_ui.c (ui_setoptions):
* ed2k_hash/options.c (options_print_help_screen_and_exit):
Add -- command line option to separate option arguments from
filenames, so that it's possible to hash files that start with a
hyphen (without using an absolute path or ./-foo). Closes: #1462750
