Markdown clip download fails if website does not have a 'title' tag

Despite a missing <title> tag the browser displays a reasonable title. However, the website cannot be clipped because pageTitle is empty. The extension silently fails to download anything. The solution appears to be to make sure the DOM string passed into getArticleFromDom (background.js) contains a <title> tag.

+1 for that
Got similar behavior when tried to save some txt files which, obviously has neither {title} nor {pageTitle}.
There are two separate issues for that:

1. If resulting filename is empty, there should be visual indication of an error, not just silent "do nothing" behaviour. Currently it's extremely easy to miss the fact that page is not actually saved.
2. It would be nice to have some syntax for fallback or conditions. For example, I would like extension to try {title}, {pageTitle}, {baseURI} in this order to create a file name.
