PropertyEvaluator: eval strings, fix test, so it doesn't rely on any specific evn key
launcher: replace flavour with profile, a list of ServiceStarter and Monitor configs;
don't exit on main's end;
don't rely on env RIO_HOME - WIP

ServiceStarter: remove code that changes system properties, leave just warnings;
remove loading from directory;
remove profile (move to Launcher)

AbstractServiceDescriptor: don't guess RIO_HOME, use system property or warn if none set.
