Bug 4354: Cannot edit existing issuing rules

This patch adds javascript which pulls the values from the
chosen row of data and populates the last row's form with
that data. Some changes have been made to the markup to
better accommodate this.

Possibly missing is some kind of visual feedback to the user
that the edit action is taking place in a different row from
where they clicked. Comments are especially welcomed on
this aspect of the interaction.

The original author of this patch is Owen Leonard <oleonard@myacpl.org>

Test Plan:
* Edit an existing circulation rule
* Delete a circulation rule
* Create a new circulation rule
* Create a new circulation rule that is a dup of an old one
and make sure that it still overwrites the old rule like before
