Subsantial fixes and improvements to budgeting

 1. A bounded budget "from DATE to DATE" will now generate entries
    throughout that entire range, if it is triggered.

 2. An unbounded budget begins, as before, in the timeframe of the
    reported posting which triggered it, but now continues until the
    present date.
