Add invoice_edit.php support on recurring_list.php for bulk recurring item edits
So, invoice_edit.php is totally awesome, I just basically want it on the recurring_list.php page to make bulk recurring item adds/edits easier. I know this'll require displaying the bill increment (how often the item is billed, every XX Years, XX Months, etc), but it'd be totally great to have. I'll see if I can't start on this task and ideally break the whole billing repo, will prod ya when I do so.
