HD Extensible Social Profiles Widget

This is a short plugin which adds social profiles to the customizer so users can add the links of their social profiles. It also creates a widget to output these links in a widgetised area.

This is a great example of a starter plugin written in an extensible way. The extensible-changes.php shows how other developers can make use of the extensible functions.
