Issue MDL-47022: Implement "Export since" filter on grade export
The current grade export feature does not have a way to filter the results by date. While working on MDL-46599 we found the necessity of create a new filter by date and time, in order to fix this bug properly. The main concept is allow users to export grades from a past date to now, and save the last export date for further reference. Another benefit of this new feature would be standardize all export formats (OpenDocument, Plain Text, Excel and XML). We're still considering about the possibility of replace the *Export new or updated grades only* by this date filter. However this could turn this issue too expensive because the XML structure is different of other export formats and is being used by OU and it rely on a config: *gradeexport*.
