Add scripts for installing Windows Management Framework 5

[junaidali]

Thanks @jborean93 for creating these extremely useful scripts. I've added two new scripts for installing windows management framework 5.1. The Install-WMF5.ps1 powershell script is for local installation of WMF 5.1 as Microsoft does not support running it over remote connection. To resolve this issue I've created Install-WMF5.vbs which is native vbscript that can be run on machines that don't have PowerShell installed or is corrupted.
