More work cleaning up and testing the use of charge waivers, as well as security deposit utilizations. Much of this was just around the concept of determining balances, which wasn't / isn't very straightforward. It's not hard to calculate a balance for a particular sitation, but it is difficult to generalize. I think it's reasonable as it now stands, but the StatementEntry::stats algorithm is certainly subject to change. Also, I didn't double check every case which called the stats() function, so I highly suspect we'll find cases where the code is not expecting the new return values, either symantically or logically.
