Enable "Custom Post Widget" buttons eachtime tiny mce is used

Hello,

This plugin is very helpful.

You choose to add the popin only in ‘post.php’, ‘page.php’, ‘page-new.php’ and ‘post-new.php’.

Why not enable the pop everywhere tinymce is enabled ?

In this way your plugin will work on our custom admin page too.
(like admin.php or settings.php too if needed)

I propose to edit post-widget.php:
Comment your last line and just add 1 line.

// Only add content block popup action on page and post edit
/*
 if( !defined( 'CUSTOM_POST_WIDGET_CURRENT_PAGE' ) )
	define( 'CUSTOM_POST_WIDGET_CURRENT_PAGE', basename( $_SERVER['PHP_SELF'] ) );
if( in_array( CUSTOM_POST_WIDGET_CURRENT_PAGE, array( 'post.php', 'page.php', 'page-new.php', 'post-new.php' ) ) ) {
	add_action( 'admin_footer', 'add_content_block_popup' );
}
*/

add_filter('mce_external_plugins', 'add_content_block_popup');

That seems to work. (all page with tinymce have your plugin working on it too)

Thank you to share your work.
