Moved a lot of generic preview code to the new files gimpmiscui.[ch] so it will be easier later to port these plug-ins to the new (not yet finished) effect preview widget.

* libgimpwidgets/gimpdatafiles.c: s/S_ISLINK/S_ISNLK/ (was never
compiled before Hans fixed the #ifdef).
2002-11-30 Maurits Rijk <lpeek.mrijk@consunet.nl>
* plug-ins/common/flarefx.c:
* plug-ins/common/jigsaw.c:
* plug-ins/common/nova.c
* plug-ins/common/wind.c
* plug-ins/common/illusion.c
* plug-ins/common/glasstile.c
* plug-ins/common/max_rgb.c: replace preview code by calls to libgimp
* libgimp/Makefile.am: added gimpmiscui.[ch]
* libgimp/gimpmiscui.[ch]: new files. For now contain effect preview
stuff collected from several plug-ins. Warning: this is NOT the new
effect preview widget I'm writing, just a first step to cleaning up a
lot of plug-ins.
2002-11-30 Hans Breuer <hans@breuer.org>
* */makefile.msc */*/makefile.msc : updated
