Subject: M_AMPHIBIOUS now means both "land creature can swim through deep
 water" *and* "deep water creature can walk on land".

Most of the supporting features neccessary for the "earth worm" FR
[1766532] have been implemented, except for "fleeing towards walls".
However, no work has yet been done to update the monster AI to
work well when a monster is fighting an earth worm.
