- Bug 5531.
 caparesponse.pm
  - For stringresponse: (case (in)sensitive) computer's answer available
    in detailed submission display.
  - Student username in warnings on control characters etc. renamed $sname
    instead of $name (already in use in different scope) to improve code
    readability
  - computer answer available for legacy stringresponse submission (e.g.,
    for bug 5531 detection script -see neutrinohavest.pl)
    if grade_retrieveanswers included in form for answer target.

 default_homework.pm
  - fix detection of control characters in answers - answers will be in
    an array
  - computer's answer returned by &caparesponse_check_list()

 loncommon.pm
  - &format_previous_attempt_value() handles display of computer's answer.
  - fix typo in phrase for localization (no current translations in
    localize/*.pm to update).
