Don't swallow plaintext when formatting links

It used to be that with non-richtext adapters, like e.g. IRC, we'd
swallow the human-readable text and display only the URL. However,
that text is often super useful - it contains, for example, issue
titles.

So we just put the URL in parentheses.

Fixes #44
