Paste HTML-formatted clipping as plain text

[aecreations]

Clippings 7.0 introduced the ability to copy clipping text to the clipboard, and if the clipping is formatted with HTML tags, allow users to copy as HTML-formatted text or plain text (without any formatting).

Since the jQuery library is now included in the background script so that HTML formatting can be stripped when copying an HTML-formatted clipping as plain text, it should be possible to do the same for pasting an HTML-formatted clipping as plain text.

Along with this new paste option for HTML-formatted clippings, also reintroduce the ability to prompt the user for the paste formatting option when pasting an HTML-formatted clipping. This would bring back a feature that existed prior to Clippings 6.0.
