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.
the current code never reaches lines 130 because it abort()'s on line 124 if the language is not en_us or NL. So executing it on a session with de_AT will always enter this if statement
```
if sysLang != "en_US" and sysLang != "NL"
    print_error ("System language not supported, only English (en-US) and Dutch (NL) are supported, you can specify the targets system translations in the options A_TRANSLATION (Allow) and ACF_TRANSLATION (Allow access for)")
    abort()
```
