deal with the output by removing params where possible and elsewhere
by adding XP_UNUSED macro wrapping __attribute__((unused)). There
should be NO change in function in spite of the large number of files.
change, then juggle again so the outcome is random. This works on Palm
because draws are not cached: if two players wind up not moving you still
see them move then move back.
changes (shifting util functions around) that follow from that. Back
version number down to 4.1.5 since that'll be the next shipped from this
branch. Add juggle button to newgame -- the whole point of this.
