- When one field depends on another for the min or max date, set it immediately even if the first field doesn't have extra datepicker settings.
- Fix: The inline datepicker wasn't always being displayed depending on the settings.
- Fix: Use the correct start and end years if the years setting is different from the min and max dates.
- Fix: More reliably set the minimum and maximum dates.
- Fix: If a minimum date is set don't force it for the default date.
- Fix: A PHP error that was showing when a field had no settings saved.
