Use a common funcion for all monster healing

Browse Source 
Previously, the code for monster healing was repeated every time it
was needed; this commit sends it all through a common function, which
will make it easier to make changes to how monster healing works in
the future.

This is just a code reorganisation and won't have any gameplay
effect unless I made a mistake.

/* Heal the given monster by amt hitpoints, unless it is somehow prevented
from healing. "overheal" is the maximum amount by which the max HP will
increase to allow for the healing (the resulting HP caps at max HP +
overheal, and the max HP stays the some unless it needs to increase to
accommodate the new HP). Overhealing the player is not currently
implemented by this method.
This function should only be used for situations which are conceptually
heals, rather than other situations where a monster's HP is set, so that
"prevent healing" effects work correctly. In particular, it should not
be used for cases where a monster's HP is restored upon revival, or when
a monster is created. It also shouldn't be used for lifesaving, which
overrides "cannot heal" effects.
amt and overheal must not be negative (0 is allowed, and a very common
amount for overheal). Returns the number of hitpoints healed. */
