Title: Add the ability to select the file format (CSV or XLSX) in the export form

Heres the modifications I was talking about in the Google group.

I also added a "Select All" and "Select None" links to the export form to select all or no column checkboxes when using jquery.

Feel free to clean it up or make improvements.
