Add ability to copy pasteboard contents to the pasteboard (as one big item)

[petrock99]

It would be nice to be able to copy the data being displayed in the UI (e.g. all the text for all the pasteboard items) to the pasteboard so it can be pasted directly into another app for analysis/processing/sorting/discussion. The old PasteboardPeeker used to do this and was very handy.

Maybe save as XML or JSON or raw .txt file containing each pasteboard item identifier with its associated value/text. If the value is a picture or some other non-text data then maybe save it as a side file with a path to it in the xml/json/txt file.

Thanks.
