UPROPERTY Serialization Specifiers issue

[Daekesh]

The comments on (and order of) of the serialization specifiers seem to imply that Transient (and other specifiers) will not allow text export. However, only TextExportTransient actually blocks this. I'm not sure where DuplicateTransient is actually used, but duplicating actors, for instance, is done entirely through text export/import and does not use this flag. Which flag copy/paste uses is entirely implementation dependent so other copy/paste actions have to be looked at on a case by case basis to see which flag their action actually use (Text, StaticDuplicate, etc.)
