Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.
