Add support for Windows 7 and Windows Server 2008 R2 by installing WMF and .NET Framework

The Factory.ps1 script fails for Windows 7 and Windows Server 2008 R2
mostly because some of the code only works in PowerShell 3.0 and above,
so this change checks the PowerShell and .NET versions and if required,
downloads updated software and installs it for Windows Management
Framework 4.0 and .NET 4.5.2.
