Don't buy WinRT if you can use the free version.

We have updated the WinRt download page (http://www.netvigilance.com/winrt) to make it clearer for users to see and understand the difference between the paid version and the free version.

Explained the difference between RT and winRT, and put a little seperation between the paid version's link and the free version's link, to avoid people paying when they only really need the free version.
