Log:
Offer the use the option to move metadata stored in added fields to notes field when changing course with which a resource (from portfolio files) is associated.
Code used to store updated metadata file moved from &present_editable_metadata() to a new subroutine: &store_metadata().
&store_transferred_addedfields() added - used (for portfolio files) to append metadata in any added fields with data (for existing course association) to notes field, when course association changes (if requested by user).
