_s: Provide a context for the comments title strings.

There are languages that have more than one plural form. Sometimes these
languages need to add the %1$s placeholder in the original singular
version to help differentiate between these plural forms.

In case the original singular version ('One thought on
&ldquo;%2$s&rdquo;' in this case) is used elsewhere, the translation
with the faulty %1$s will be used, possibly ending up with the
placeholder not being replaced.

The context will prevent that from happening by seperating the strings.

This change points the URL back to the main `_s` GitHub repository where it is now being developed on. 
Alternatively it could point to underscores.me
