Fix options handling : real space resistant parsing. Values surrounded by double quotes in key-value pairs. Dialog stops messing with other columnns. OnChange code overriden in PythonFileCTNMixin so that content of options can add Alaram and StoredValue calls. + various rework in SetOption GetOption to avoid being poisoned by user input
