Fix PHP 8.4 compatibility issues in Sensational theme

- Fixed deprecated WP_Widget constructors in all widget files
- Changed $this->WP_Widget() to parent::__construct() in:
  * widget-social.php
  * widget-fblikebox.php
  * widget-googleplus.php
  * widget-tabs.php
- Fixed old-style constructor methods to __construct() in:
  * widget-ad125.php (mts_Ad_Widget -> __construct)
  * widget-ad300.php (mts_ad_300_Widget -> __construct)
- Fixed for loop syntax error in widget-tweets.php (for(i; -> for($i = 1;)
- Enabled registration for ad125 and ad300 widgets
- Added new 'After First Paragraph' widget area for in-content ads

All widgets now compatible with PHP 8.4 and editable in WordPress admin.
