I was trying to reproduce the reported "no monster to remove" warning
from remove_monster() when a mounted hero was knocked off jabberwocky
steed but so far haven't been able to.
While trying, I came across a more minor bug. The hero got knocked
off a flying steed and got feedback of "you fly off" rather than
"you fall off". Flying capability came from the steed and dismount
feedback is aware of that but calls u_locomotion() which isn't. This
commit fixes that.
This adds some groundwork (DISMOUNT_KNOCKED) for better dismount
control. With a map fragment of
|....
|.Du.
|....
I got knocked off my steed by the attacking dragon and ended up with
|..@.
|.Du.
|....
It would be better to prefer spot 1, then the 2s, then 3s, then 4s
(not sure about farther spots if none of those are available)
|.432
|.D@1
|.432
when forced to dismount by knockback. This does _not_ implement that.
