Update to 2.10.0
    
    Bugfixes
      * argbash-init is able to handle empty string as the only argument without
        being puzzled.
      * Error handling of script working directory detection now more robust.
    New features
      * Argbash in the container has no longer the terminal output limitation
        caused by the crlf line ending.
      * The ARG_USE_PROG implementation was missing. Therefore, it was implemented
        as ARG_USE_PROGRAM using a slightly different interface.
