Bug 9117: Reports hierarchies management improvements

- Filter by groups using tabs
- Filter by subgroups using a dropdown list under each tab
- Allow to create new group and subgroups when building a new report or
  editing an existing report (no need to go through admin AV interface)

+ Possibility to duplicate a report (new link in the table)
