REVISION SUMMARY
  This is more of a cleanup patch that removes the obsolete m_canBeEnabled
  member variable which was a leftover IMO from a time where readOnly fields were
  shown as disabled. readOnly fields are invisible, not disabled, and the code no longer assumes that
  readOnly does not change over time.

TEST PLAN
  Tested manually and with a unittest which is part of the series.

REPOSITORY
  R223 Okular
