Title: Add subscription widget wildard

Replaces “%d” in the subscriptions widget text with the total number of subscribers to the site. This allows users to show this info however they want and not only using the pre-written message that is currently available.
This can be supported by some nice UI in the widget editor or left as a hidden feature.
If this gets in, removing the current option to display the number of subscribers should be considered.
