Internationalization

[mrwpress]

In some places, you have internationalization in place. Like /includes/admin-options.php line 48:

	add_submenu_page( 'wo_manage_clients', 'Clients', __( 'Clients', 'wp-oauth' ), 'manage_options', 'wo_manage_clients', 'wo_admin_manage_clients_page' );

See how you have:

__( 'Clients', 'wp-oauth' )

That needs done throughout the entire project in ALL files. For example /includes/admin/pages/edit-client.php line 145:

                                <h3>Advanced Options</h3>

Should be:

                                <h3><?php echo __('Advanced Options', 'wp-oauth'); ?></h3>
