[Tip] make phone as a required field during resgist or modify account info

[Guest]

if you need to make phone as a required field during resgist or modify account info,
you can do as below:

1. modify it in:address.php, modify:
protected $fieldsRequired = array('id_country', 'alias', 'lastname', 'firstname', 'address1', 'postcode', 'city');
to

protected $fieldsRequired = array('id_country', 'alias', 'lastname', 'firstname', 'address1', 'postcode', 'city','phone');

2. modify authentication.tpl,address.tpl,below black:

{l s='phone number'}
<input type="text" id="phone" name="phone" value="{if isset($smarty.post.phone)}{$smarty.post.phone}{else}{$address->phone|escape:'htmlall':'UTF-8'}{/if}" />
