Subject: [PATCH] Bug 17674: Allow UI to delete serials in batch

This new feature allows for batch deletion of serials through the UI.  The current usage is a one-by-one long game.

Test plan :
- Apply patch.
- Create at least four serials with items.
- Notice that new items have a numbering pattern and a date in the enumchron field.
- Use the button Delete selected issues for the following steps.
- Delete a serial and its associated item.
- Confirm the serial and item are gone.
- Delete a serial and not its item.
- Confirm the serial is gone.
- Confirm the item is still there and the date part in the enumchron field is gone.
- Delete the two lasts serials.
- Confirm they are gone.
