Comment 2 for bug 667166

There are 2 problems here:
- in the fields_view_get of account_move_journal.py some strings are not translated with _(), this will be fixed
- in the fields_view_get of account.move.line, which takes the definition of columns from the Journal itself, the (user-defined) field names are not translatable. We should see if these names should be translatable, or if we should force the (translated) name of the original field. Some other minor parts of the view need translation too (sums, etc.)
