Pasi Kallinen 4a01c8fbd7 Monster list iterator 
Add some basic functions to iterate through the monster list,
ignoring dead monsters. Mainly just to allow splitting up code
into discrete functions.

Not quite happy with the get_iter_mons_xy - should probably have
a pointer to iterator data struct, which gets passed through instead,
but this works for now.

an encumbrance check when they're healed. However,
while dismounting, first steed's legs get healed,
then hero is dropped to floor and a new encumbrance
check is made [in dismount_steed()]. So don't give
encumbrance feedback during the dismount stage
because it could seem to be shown out of order and
it might be immediately contradicted [able to carry
more when steed becomes healthy, then possible floor
feedback, then able to carry less when back on foot]. */
