Add Windows post module for reading/searching Outlook e-mail

This module allows to read and search e-mails present in Outlook installations. It is using powershell in order to search the e-mails.

When connecting to Outlook using powershell, a security popup appears. WinAPI is used to automatically click on the popup, so access is allowed.

This module is tested on Windows 8.1 x64 with Outlook 2013.
Would you mind to update this script too, to leverage all accounts instead of only the first one?

I think the output also needs to be reworked and only show the basic details like From, To, Subject and Body (formatted as a list). The current output is more like a debug output.
