Description of problem:
It would be handy to have a feature whereby, if one hovered one's mouse over a bar in a Gantt Chartt, the name of the task would appear in a pop-up "tooltip" style box.  


Currently, the Planner Help file states that, "The Show Guide Lines option displays horizontal guide lines in the  Gantt chart to help the user visually line up the chart bars with the task list on the left hand side of the window."

That notwithstanding, with long bars (for projects of lengthy duration) being viewed on widescreen monitors, (or possibly spanning dual monitors), the ability to see a pop-up "tooltip" referencing the name of a task would be handy as the user would not have to trace the lines back with his or her eyes.

Version-Release number of selected component (if applicable):
0.14.4

How reproducible:
Feature does not currently exist.

Steps to Reproduce:
1.  Hovering the mouse over a bar in either the Gantt Chart or Resource Usage views.
  
Actual results:
Does nothing.

Expected results:
Should generate a pop-up "tooltip"-style box displaying the name of the task so the user does not have to trace back along the gridlines all of the time.  This would add a little more polish and usability to the application.
