Bug 15231 - Import patrons: Remove string splitting by html tags to avoid weird translations

Some of the strings in Home > Tools > Import patrons contain html tags and therefore are
splitted in the translation tool. This makes it nearly impossible to create correct translations
from the partial strings.
Additinally, the notes for Extended patron attributes never displayed (due to a bug).

To test:
- Apply patch
- Enable Syspref 'ExtendedPAtronAttributes'
- Go to Home > Tools > Import patrons and verify, that the Notes at the right of the
  screen make sense
