Civi button in WP Editor with depricated calls

The way the Civi button is being called & used currently is using deprecated functions. We are looking at changes in 3.9 which includes a big TinyMCE update to determine what the best way to make changes to the deprecated call is. For reference the they are: media_buttons_context & thickbox, more documentation here:

• https://codex.wordpress.org/Function_Reference/wp_editor
• https://codex.wordpress.org/ThickBox

Until some of the bugs are ironed out in on the WP side, it would make sense to wait a to see how the most recent changes affect the wp_editor to determine the best way to update these calls.

The insert-civi-things button doesn't appear in WP 3.9. Pretty easy to fix in civicrm.php:

add_action( 'media_buttons_context', array( $this, 'add_form_button' ) );
becomes:
add_action( 'media_buttons', array( $this, 'add_form_button' ),21 );

and in add_form_button():

return $context . $out;
becomes
echo $out;

I'll try to create a patch (haven't done one before)...
