Bug Fix - confirmation not processing newline
Bug Fix - confirmation not processing newline

- Fixed bug where util.cpp:confirm was eating newlines, and not
  rewriting the prompt.  Consequently, after confirm asked the
  question, and the user hit <Enter>, nothing was displayed but
  the newline.  Now uses std::getline.
