The 'now' values got broken again somewhere along the line. Now we need to switch the ISO format used by our SQL queries back to the datetime format the widgets use.

Issue #1115770, Make sure filters values are switched back to ISO format so time comparisons work correctly.

Issue #998220 by jamsilver and yched, fix handling of validation in date_combo. This also fixes errors when using a date in Profile 2.

Remove extra fields from the Date field. I think the filter and argument now get the right tables joined in without that. We still need the extra fields on calendar, but now we will only add them in the calendar view.

Issue #1086582 by bojanz, summary options are in a different place now, fix the method of removing the summary option on multiple-date arguments.

There were some problems when creating a year-only date using the select filter caused by trying to create a date with zeros in the month and day. Fix the date building logic to force a valid month and day into them.
