Issue #1082658: Saving the options as arrays breaks other things. Add a custom export plugin instead.

More work on new filters and arguments, adding in the fix to include filter and argument option settings in the export.

Issue #1075890 by KarenS: Initial pass at breaking out the code into the simple filter and a complex filter that combines date fields.

Check for empty values as well as missing values for better performance in the Views exposed widgets.

Invalid or empty dates need to replace the form array with an empty string. Also removing some code from date_api_sql that actually doesn't do anything.

The Views Field handling code got totally changed and everything has broken here again. Some commits to temporarily workaround the changes. I probably just have to re-do all the Views handling from scratch to better integrate with the way that Fields and Views now work.

Add some error trapping in case the parent dateObject is unable to make a date out of a string to avoid showing the user errors.

Views changed the way fields are handled, need to do some changes here to accomodate that. This is not necessarily the best way to handle things, but no point in re-working it until Views quits changing the way fields are handled.

#1021512 Fields on user that don't show up on registration form still run through hook_field_validate. Don't validate missing values.
