PowerShell Installation Guide for Windows

PowerShell comes in two flavours - PowerShell Windows and PowerShell-Core. You are recommened to download PS-Core, as it is the one in active development by Microsoft and thus have the latest features. `ocwd` downloads work faster with PS-Core (thanks to multi-threading!)
