Here's a report to help with escrow balancing

Better PayPal penny testing
Add images needed for Balanced Payments sections
Here's yet another attempt to placate PayPal

It turns out there's another twist to the MassPay penny saga: in some
situations (when amounts are small enough?), the fee is rounded to what
we wanted it to be anyway. See #2296 for a description.

This commit takes a whole 'nother approach to fee computation. Instead
of computing / 1.02 of the target and then fudging it from there, we
take a much simpler approach. We start at a penny under the target and
work down from there a penny at a time until we find a value that works.
Less efficient but safer.
