FText: Expose multiline property in blueprint metadata

Yeah those cases make sense.

Sorry, I wasn’t clear RE: refactoring it; I didn’t mean a custom registry for providing a nice user interface for custom metadata; doing the refactor would make it easier to expose metadata at all, as instead of adding a bunch of custom slate, it could either just be a reflected array of structs or a tmap, along with a couple of lines of code in a read/write function that copies the value to/from the persistent storage in the variables array.

Cheers,
