Bug 13625: Change messaging preferences descriptions according to RenewalSendNotice

Sending out renewal notices depends on the RenewalSendNotice and the
patron having the checkout notice checked in their messaging
preferences.

To test:
- Apply patch
- Take a look at the messaging preferences table on the following pages:
  - OPAC > patron account > your messaging tab
  - Staff interface > patron account > details tab
  - Staff interface > patron account > edit patron
- Toggle the RenewalSendNotice preferences
  - The label on the last notice should switch between "Item checkout"
    and "Item checkout and renewal" depending on the pref setting
