 Bug 15365: Translatability: Fix issue on Administration > Circulation and fine rules

Fix translatability issue on smart-rules.tt to prevent odd translations (Sentences
splitted by tags and newlines).

To test:
- Apply patch
- Go to Administration > Circulation and fine rules
- Verify that the lines "Note: " and "Important: " below "Default holds policy by
  item type" make sense and are not splitted by tags and (in html) by newlines.

(Amended to fix commit message)
