Summary: LOOM: silly walks

Initial Comment:
ese buglets happens in recent CVS snapshots, but I
think it's been like this for quite some time now. I
have a nagging feeling that they are related, which is
why I report them as one bug instead of three.

1. When Bobbin wakes up in the cell in the Forge, he
starts walking on the spot, without getting anywhere.

2. Then, after he has twisted or unsharpened the final
sword, two guards start walking toward him. They should
end up on either side of him, except the one on the
right keeps walking an imaginary downward slope, so he
ends up somewhere near the lower left corner of the
picture area.

I added some debug printf()s to startWalkActor(),
classChanged() and o5_setClass(), and this is what I found:

0x8189a10: o5_setClass cleared ignoreBoxes and forceClip
0x8189a10: classChanged(22, 1)
0x8189a10: classChanged(21, 1)
0x8189a10: startWalkActor(304, 47, -1)

(So far it works. The right guard's ignoreBoxes is
true, so he walks towards the destination in a
straight, diagonal line.)

0x8189b90: o5_setClass cleared ignoreBoxes and forceClip
0x8189b90: classChanged(22, 1)
0x8189b90: classChanged(21, 1)
0x8189b90: startWalkActor(161, 47, -1)

(The left guard's ignoreBoxes is also true, so he will
walk in a straight horizontal line towards his
destination.)

0x8189a10: o5_setClass cleared ignoreBoxes and forceClip
0x8189a10: classChanged(21, 1)
0x8189a10: startWalkActor(193, 47, -1)

(The right guard can't walk to the intended destination
because his ignoreBoxes is false, and the destination
is outside all boxes.)

So I can easily fix this second problem, but all such
fixes of mine have either been specialized hacks, or
they have (probably) broken other stuff as well.

3. During the confrontation with Chaos at the end of
the game, by the time Bobbin says "Over my dead body!"
Chaos will have moved to the center of the screen.
Then, after she replies "Preference noted.", she
suddenly pops back to the left side of the screen again.

I'm attaching some save games. The twisting draft is "c
f c c", and the opening draft is (as always) "e c e d".
