UML classes: responsibilities not rendered

[Neil Zanella <nzanella cs mun ca>]

Hello,

The UML class properties window should have yet another tabbed pane called
"Responsibilities" in addition to the "Class", "Attributes", "Operations",
and "Templates" tabbed panes. According to the UML 1.3 specification and
the Unified Modeling Language User Guide by Grady Booch, James Rumbaugh,
and Ivar Jacobson, p. 53, responsibilities are used to describe the
purpose of the class and can be rendered as an optional separate
compartment at the bottom of the UML class below the attribute
and operation compartments.
