removed reaper, still have table_bug #339

Removing any one of the remaining Level 1 monsters (Wisps of Pain, Swarm of Daggers)
or the Chain Golem or the Jumping Bomb caused the bug to disappear.
(It's possible the Blood Ape could be removed, but that would require changing the test)
removed some mindslug-related code, but not the mindslug - for table_bug #339
