Deprecated PHP4 style constructors

WordPress 4.3 deprecated PHP4 style constructors in widgets.

This theme is throwing notices because of non-updated constructors:

( ! ) Notice: The called constructor method for WP_Widget is <strong>deprecated</strong> since version 4.3.0! Use <pre>__construct()</pre> instead. in /wp-includes/functions.php on line 3457
