DrJava Legacy SVN Repository

Fixed two issues with the Javadoc All Documents dialog:
- It would only prompt you to create the directory (assuming it doesn't exist) if it was left as the suggested directory. If it was changed, it would tell you the directory didn't exist, and not do anything (whether you hit OK or cancel). Now, the dialog will always prompt you to create the directory if it doesn't exist.
- The prompt to create the directory contained a typo that resulted in a \n being printed in the dialog.
