review accounts with failed credit cards

[chadwhitacre]

We're looking for more suspicious accounts here. Should take a pass through cc failures to make sure we aren't missing any. Having that info in the db (#364) would help this, but I think for now we should do it as a one-off.

Bullet to collect usernames from payday logs:

grep fail * | sed -e 's/.*Charging \([^ ]*\) .*/\1/' | sort | uniq

That's in the directory containing payday log files.

57 accounts have failed at least once.

I reviewed those 57 accounts and have satisfied myself that they're legit, apart from the ones already flagged.
