Some OWA Servers require NTLM and Basic authentication

Thank you very much for doing this! It is very useful.

Some servers require NTLM and Basic authentication. In this case, the Authorization: NTLM header must be sent before the Authorization: Basic header.

Please consider adding an authorization_type to the class so affected users can use something like this:

401c401
< curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM);

---

> curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM | CURLAUTH_BASIC);

If you wouldn't mind submitting a quick commit/pull request I'd definitely welcome the change!

In order to use this class with microsoft live 365 I had to make this change also ie replace

curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM);
with
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM | CURLAUTH_BASIC);
