Change the Table column to sortable.

Thanks for this plugin. I use it to let users help me fight spam.

I modified line 142 so it looks like the following. Which, allows the column to be sortable like the rest of the table.

add_filter('manage_edit-comments_columns', array( $this, 'add_comment_reported_column' ) );
add_filter('manage_edit-comments_sortable_columns', array( $this, 'add_comment_reported_column' ) );

Thanks,

Eric
