Use uimenu objects for default menus in Qt toolkit
* Menu.cc (Menu::Menu): use QAction name to tag wether a menu is a builtin
or a custom menu based on the uimenu "tag" property.
* Figure.cc (hasUiMenuChildren): Remove
(Figure::editCopy,Figure::fileCloseFigure,Figure::fileSaveFigureAs,
Figure::copy_figure_callback, Figure::save_figure_callback): Remove
(Figure::createFigureToolBarAndMenuBar): Don't create menus not backed by
uimenu objects
(Figure::showMenuBar): Make use of the QAction name for menu triage. Use the
difference between previous and current menubar height to adjust the figure
position.
* __add_default_menu__.m: Create default menus for Qt aswell. Change actions
in the "Edit" menu to "Tools" menu. Add a few actions in "Edit" menu. Rename
uimenu handles to hui as is conventional in Octave code.
* clf.m: With "reset" option, don't unnecessarily delete/recreate default menus.
