Add an option to abort when a panic alert occurs

Prompted by https://dolphin.ci/#/builders/24/builds/985

A 1-character typo in a recent PR caused FifoCI builds to break
horribly and spew millions of panic alerts until buildbot crashed.

This PR adds a new config option -- defaulting to off -- that allows
Dolphin to abort early on when a panic alert occurs instead of
continuing forever.
