Title: introduce MAPI oder HTTP support for squid-reverse

Microsoft introduced a new protocol in Exchange Server 2013 SP1 called MapiHttp (codename Alchemy). This is an Office 365 development to replace the traditional RPC/HTTPS protocol used in Outlook Anywhere but has been made available to on-premises Exchange 2013 SP1 as well.
