Write a $contact.quote widget that renders a blockquote for something somebody in your contacts said, given a body containing the quotation and a contact parameter containing the name of the contact's tiddler.

The widget should show a link to the person's tiddler, with text matching their name (taken from the caption field of the tiddler if it exists, or the title if it doesn't), then a colon, then starting on the next line a blockquote.

Tip: Use the <blockquote> HTML element, not one of the wikitext syntaxes – $slot doesn't play nice with wikitext formatting here.
