** SHIELD AND CLOAKING DEVICE CONTROL
**
** 'f' is one for auto shield up (in case of Condition RED),
** zero for shield control, and negative one for cloaking
** device control.
**
** Called with an 'up' or 'down' on the same line, it puts
** the shields/cloak into the specified mode. Otherwise it
** reports to the user the current mode, and asks if she wishes
** to change.
**
** This is not a free move. Hits that occur as a result of
** this move appear as though the shields are half up/down,
** so you get partial hits.
