I decided I didn't like being able to change what errors halt. We need to count on ERRORs halting the script and we want to count on WARNINGs not halting the script so that we don't have to undo db changes if we're part way through, etc.

So, now errors halt and nothing else does. You can now change whether or not to display WARNINGs and NOTICEs.
