Subject: More repl work.

Hardened the repl against a bunch of erroneous conditions. Added a
:reset command which causes the repl to forget everything you have told
it. Added classloader tracing when repl tracing is enabled. :reset is
not that useful in its current form but it's the precursor to something
more interesting. No review.
