Subject: Next syscons update (given up on numbering :)

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.
