Optimization of ConfigBase::equals() to not create intermediate

list of modified options.

Optimization of DynamicConfig::equals(), ::diff(), ::equal()
to iterate over the two compared std::map trees instead of
first generating a list of keys and then searching for each key
in the respective map.

Optimization of PresetCollection::current_is_dirty() and ::saved_is_dirty()
to call DynamicConfig::equals() instead of ::diff().
