Bug 7679: circulation statistics wizard improvements

- Add patron branch to the list of possible rows, columns, and filters
- Add extended patron attributes to the list of possible rows, columns,
  and filters
- Allow to group period by hour
- Allow to translate filter names

NOTE: Removed signed off, since I believe I have dealt with the conflicts.
      Retesting required. Found some comments C4::Date that I missed.
      line prepatch 194/ postpatch 233 seems to be where the major
      conflict is.
