Add action hook to get_inline_data()

[mensmaximus]

Working with customs fields in quickedit for custom post types would be much easier if one could add custom data to the get_inline_data() function in /wp-admin/includes/template.php. An action hook like do_action( 'add_inline_data', $post ) right before the closing div would be a great enhancement.

This functionality will be very useful

First attempt at a patch. Not sure how I messed up the first diff.
