Brings back the classic WordPress text widget without TinyMCE. This is based on the code from WordPress Ver. 4.7.5
Functionality is exactly the same as the pre-version 4.8 text widget. Additional default functionality includes shortcode execution and custom class filter.
Note: This widget uses PHP namespaces to prevent conflicts with other widgets of a similar nature. PHP namespaces are only supported in PHP Version 5.3.0 and higher. If your site uses a PHP version earlier than 5.3.0, do not install this widget unless your PHP version is upgraded first.
