Added cached fields for charged_through and paid_through dates of a lease. Also, added the ability to dynamically determine whether a unit is late or not. In reality, we really need this to be part of the lease, not one of the status types for unit. The sitemap, however, is driven from unit information, so it's not clear whether we should move that information or not.
