#21 element_panels.properties references nonexistent class

[radtken]

On line 44 of the element_panels.properties file the follow line appears:
net.sourceforge.cruisecontrol.ProjectConfig=net.sourceforge.cruisecontrol.gui.panels.project.ProjectTabbedPanel

The ProjectConfig class no longer exists in the net.sourceforge.cruisecontrol package. This issue does not effect runtime. All references to this class should be updated to the ProjectTabbedPanel.
