QAction defaults menu role to TextHeuristicRole, which causes qt to
guess the menu role based on action title. And titles start with
'Config', 'Options', 'Settings', etc. will be considered as preference
menu. It seems some non-english translation causes the wrong action be
chosen as preference, such as 'Treeview actions'.
This commit just applied a temporary fix to default to QAction::NoRole
for GroupCommand. If there is ever some GroupCommand need to be a
system menu item on macos, we could add some command bit flag for that
purpose.
Add the optional Qt::MSWindowsFixedSizeDialogHint parameter to all uses of the QInputDialog::getX static functions to silence a Qt/Windows debug mode warning about QWindowsWindow::setGeometry: Unable to set geometry. Increase the size of the unit calculator to eliminate the same warning. Finally, call adjustSize() on the "Unsaved Changes" dialog to silence the warning.
This commit adds SVG files with icons for these commands. Also, it makes the necessary changes on CommandDoc.cpp, CommandWindow.cpp, CommandStd.cpp and resource.qrc files.
