Don't allow to set service retirement date to the past
Don't allow to set service retirement date to the past

This fix initializes the dhtmlXCalendarObject when setting
service retirement date in such a way that it would not
render past days as selectable.

This effectively disallows to select a date in the past
for service retirement.
