The arena now prevents undesired random monsters from being placed by telling

pick_random_monster() to try something else, rather than by culling them after
they're placed.

By default the arena prevents zero xp monsters from being randomly placed.  To
allow them to be placed use the spec tag "allow_zero_xp".

Removed the arena spec tag "alert", since it's no longer needed.

Added the arena spec tag "cycle_random", which if set causes
pick_random_monster() to cycle through all the monsters valid for the level_id
chosen as the arena's place.  Produces a greater variety of monsters when
using test spawners.

If arena mode is dumping message to the output file then prefix error messages
with "ERROR: " and diagnostic messages with "DIAG: "
