ReadMe is incorrect for Visual Studio 2012

[Ash Earlz]

I've found that using copying the raw URL link and pasting it into Visual Studio 2012 Premium doesn't work on Windows 8 x64. This appears to be a bug in Visual Studio because the dialog just closes, with no action having taken place.

I suggest adding a note or something to indicate you must download it and then import the downloaded file

Thank you. I updated the instructions to instruct to download the file instead of copying the url. It's simpler that way.
