lp1034058 Disable Renewal Due Dates in the Past

Apply minimum date and an out of range flag to prevent
selecting or inputting a past date when renewing items from
Circulation->Renew Items or Patron->Items Out->Actions->
Renew With Specific Due Date.

To test
-------
[1] Create a loan.
[2] From the patron's Item Out page, use the Renew With
    Specific Due Date action. Note that the date widget
    will allow you to specify a due date in the past.
[3] From the Circulation -> Renew interface, note that
    the date widget will also let you specify a due
    date in the past.
[4] Apply the patch and repeat steps #2 and #3. This time,
    a due date in the past cannot be entered, both via
    the calendar button and by direct entry in the text
    box.
