Task "note" icon as icon next to the task name

[carloscadux]

Hi.
Now that GanttProject can show alerts and colors as icons next to the task name, I'd suggest the "Note" icon also be shown there (see screenshot).
By hovering over the mouse on the note icon, a tool-tip would pop-up showing the note content.
Currently, the note icon appears on the very right of the Gantt Chart, making it difficult to visually match at a glance the icon with the respective task.
