The ActionManager is a singleton which tracks all actions throughout the project.
It allows other parts of the SwingApp module search for actions, get action properties,
access the list of components bound to actions, and create/update/delete actions.
There is one ActionManager singleton per project.
Reads and writes data according to the ResourceMap specification.
One DesignResourceMap instance manages properties files at one level of storage.
There are three levels as defined by the app framewrok: class, package,
application.
This panel is show inside the action property editor dialog when the user

Jumps to source of the action set to the currently selected component.
If no action is set (but the component has action property), the property
editor is opened.
