Added GUI components for adding comments to defects.
Merge remote-tracking branch 'origin/dev-exemplar-comment-manager' into dev-exemplar-add-comments
Comments can now be added using Janeway. The DefectPanel updates immediately to display new DefectEvents (comments or changes).
Fix for issue where DefectPanel GUI could break when adding comments or making changes to defects.
Refactored DefectPanel so that DefectEvents are displayed in a JList, rather than as individual JPanels. There is still a small glitch, when comments are added, the last comment might run off the end of the screen.
