sickness countdown

PatR · PatR · commit 4eb05929590e · 2021-12-22T19:36:52.000-08:00
Give messages when sickness countdown has nearly expired to warn
player that hero is dying and also so that death at the end doesn't
seem so abrupt after an arbitrary period with just "TermIll" and/or
"FoodPois" on the status line.

Also, abuse constitution each turn when Sick (either variation, but
not a double amount if both).
