#1397: make attempt to change non-steerable parameters at recovery fatal error

-------------------------+--------------------------------------------------
 currently Cactus ignores, almost silently (there is a L2 warning "Non-
 steerable parameter 'ADMBase::initial_lapse' is not set from the parameter
 file but recovered from the checkpoint file"), any attempt to steer non-
 steerable parameters during checkpoint recovery. I wonder if it would be
 better to abort or at least make this a Lev1 warning. The comments in
 cckt_Warnlevel.h say:
 {{{
 #define CCTK_WARN_ABORT    0    /* abort the Cactus run */
 #define CCTK_WARN_ALERT    1    /* the results of this run will be wrong,
 */
                                 /* and this will surprise the user, */
                                 /* but we can still continue the run */
 #define CCTK_WARN_COMPLAIN 2    /* the user should know about this, */
                                 /* but the problem is not terribly */
                                 /* surprising */
 #define CCTK_WARN_PICKY    3    /* this is for small problems that can */
                                 /* probably be ignored, but that careful
 */
                                 /* people may want to know about */
 #define CCTK_WARN_DEBUG    4    /* these messages are probably useful */
                                 /* only for debugging purposes */
 }}}

 since having a parameter being ignored is indeed surprising for most users
 :-) .
