fixes #2386 update filters in users activity logs (#2399)

* Add an action filter and a date filter. 

* Additional filters on a specific object (photo/album/group) are available from their dedicated administration page.

* Performances of the page was improved : instead of loading 100k lines in activity table, we loop on 500 activity lines until 100 aggregated lines are found for the current page.
