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.
I updated the script to output the mailbox names instead of a number. It also outputs a text if nothing is found. The script also searches only the `HtmlBody` element, I think adding the subject too should be considered.

```
function Get-Emails {
    param ([String]$searchTerm,[String]$Folder,[String]$searchObject)
    Add-Type -Assembly "Microsoft.Office.Interop.Outlook"
    $Outlook = New-Object -ComObject Outlook.Application
    $Namespace = $Outlook.GetNameSpace("MAPI")
    $account = $NameSpace.Folders
    $found = $false
    foreach ($acc in $account) {
        try {
            $Email = $acc.Folders.Item($Folder).Items
            $result = $Email | Where-Object {$_.$searchObject -like '*' + $searchTerm + '*'}
            if($result) {
                $found = $true
                $result | Format-List To, SenderEmailAddress, CreationTime, TaskSubject, HTMLBody
            }
        } catch {
            Write-Host "Folder not found in mailbox " $acc.Name
        }
    }
    if(-Not $found) {
        Write-Host "Searchterm not found"
    }
}
Get-Emails "#{keyword}" "#{folder}" "#{searchobject}"
```
