Log Message:
Update to 1.5.1:
    * Now traps grabkey errors, no more X errors.
    * Xinerama support, allows x2vnc to work sanely on multi-head X displays.
    * If stdin is not a tty, read password with fgets() instead of getpass().
      This allows scripts to feed in the password.
    * New arguments -noblank and -lockdelay allows you to keep screen savers
      from activating while using your computers.
