rule element by name after group is expanded, this helps ensure stable ordering of objects in generated configuration. * Compiler.cpp (replaceClusterInterfaceInItfRE::processNext): sorting objects in rule element after cluster interfaces have been replaced, this helps ensure stable ordering of objects in generated configuration. * FWObject.h (FWObjectNameCmpPredicate): moved this class from gui-specific module to libfwbuilder as it is universally useful. It can compare FWObject objects by name and can optionally can follow references; it can be used with std::sort() to sort lists of FWObject pointers or directly sort rule elements.
