Bug 18447 - Datepicker only shows -10/+10 years

This patch makes 2 changes:
1 - Global datepicker defaulted to c-100:c+10
2 - Dateofbirth datepicker defaulted to c-100:c

To test:
1 - Open some date pickers (patron entry, subscriptions, anywhere really)
  - Make sure to check some dateofbirth datepickers
2 - Note that default is 10 years in either direction, updated when you
select
3 - Apply patch
4 - Note we now get -100 years / +10 years from current selection
5 - Now find a dateofbirth datepicker and note default is -100:+0
6 - Sign off
