Insert link page on title of the Widjet

Hi,

I added the possibility to enter the title and its link in widjet

I modified the code. Currency and checks whether it can serve.

In wppa-thumbnail-widget.php

<?php
/* wppa-thumbnail-widget.php
* Package: wp-photo-album-plus
*
* display thumbnail photos
* Version 5.0.17
