Here is a patch that implements sticky keys for fast forward and
rewind.
You need to set StickyKeys=1 in settings.txt and I found that having
FastForwardAmount and RewindAmount set to 1 works well. Pressing the
same key again will stop the fast forward or rewind, pressing any
other key also does that.
The patch is against the CVS version from Saturday.
