Bug 15984 - Correct templates which use the phrase "issuing rules"

This patch corrects two places in the templates where the phrase
"issuing rules" is used instead of "circulation and fine rules."

To test, apply the patch and view the help pages for Administration ->
Circulation and fine rules; and Tools -> Automatic item modification by
age. Confirm that the term "circulation and fine rules" is used instead
of "issuing rules."
