title: store Postman tests without passwords
body: <p>I've been using Postman to test my NetSuite RESTlets for quite a while.  I'd like to be able store my tests on the net and share them with my collaborators, but I've not been able to figure out how to get it to <strong><em>not</em></strong> store passwords.</p>
  
  <p>NetSuite uses a header like this: </p>
  
  <pre><code>Authorization: NLAuth nlauth_account=123456,nlauth_email=user@domain.com,nlauth_signature=plainTextPassword,nlauth_role=321
  </code></pre>
  
  <p>I'd like a way to put a tag in place of "plainTextPassword" and have postman prompt for and temporarily store that password and send it with the requests, but not store it with the test collections and lose it when Postman exits.</p>
  
  <p>Any ideas on how to achieve that ? </p>
