* Move the captured field into the exif module where it is created and populated.

* Create a new API event get_sort_fields that allows modules to contribute new sort fields that they manage. the only condition is that the module needs to add it to the item table.
* Changed g2_import to call this api to get the allowable sort fields
* Changed album::get_edit_form to call this new api to get the available sort fields
Partial fix for ticket #627, as the Capture date is not available until the exif module is installed.
