Building copy property (UNDONE)

// note: there is a issue 'cause we can't past the property name. (the idea was to allow passing property names at the run-time, but it looks like we are not allowed to do that in c#)

// this code was a snipped from a feature I was building to Subtitle Edit (Plugin system)
