title: Change subject on email sent through contact form in Prestashop
body: <p>I have a problem, I want to change the subject on the email that we are getting when a customer writes to us through the contact form on a webpage.</p>
  
  <p>I found the line where i change it:<br /></p>
  
  <blockquote>
    <p>if (!Mail::Send($this->context->language->id, 'contact',
    Mail::l('Message from contact form').' [no_sync]',  $var_list,
    $contact->email, $contact->name, null, null,</p>
  </blockquote>
  
  <p>I want to change it to </p>
  
  <blockquote>
    <p>Mail::l('Message from contact form - customers email')</p>
  </blockquote>
  
  <p>Anyone know what I need to write there?</p>
  
  <p>I tried like this but it returns 0 in subject:
  <strong>Mail::l('Message from contact form' - $contact->email),</strong></p>
