Refactor GaugePanel to create it's own SectionStackSection
The GaugePanel constructor now creates a SectionStackSection instead of
using a provided one.
Improve the rendering of the GaugePanel by having access to the SmartGWT wrapper
(WidgetCanvas) object for the GWT Tree (GaugeTree) directly.
Add methods to close and open the section. Also add a getter for the section.
