Major revisions to popup handling. Buttons can close menus now, plus some smaller impovements. Removed Widget module.
Moved Widget.AWidget to AChildWidget.AChildWidget and Widget.AParentWidget to AParentWidget.AParentWidget.
Removed ASingleParentWidget to improve code sharing.
AChildWidget doesn't implement IParentWidget like AWidget did.
New IPopupParentWidget extending IParentWidget for the WM and some widgets to handle popups.
Cut old popup management code.
New underMouse() function replacing highlight(); called on all widgets.
Separate menu-popup and button widgets aren't needed for menus now.
Functions returning content widgets have been moved to their own module.
Cleaned up jobs.txt.
Switched to 80 line length for Ddoc.
