Add git commit ID to beginning of loadups .dribble files. (#1778)

* Add git commit ID to beginning of loadups .dribble files.
The commit ID is put into the .dribble file in the .sh scripts. (using echo ... > name.dribble)
The changes to MEDLEY-UTILS, LOADUP-FULL, and LOADUP-LISP are to enable the passing of APPENDFLG to (DRIBBLE ... APPENDFLG).

* I hadn't saved file before previous commit.

* Add to IL:SYSOUTCOMMITS instead of to the .dribble files.

* Initialize SYSOUTCOMMITS so PUTASSOC has somewhere to put value(s)
