Rough Pass of QR code generation done.

Generates a QR code and puts it into a folder in App_Data.
I need to verify that this goes to the right url, and then I need to
make the page that loads actually display the QR code image that is
being generated.  However, it seems like the basics of all task
completion methods are now implemented.

To use this properly you will need to use nuget to install the package
for generating QR codes.  To do this, run the following command:

Install-Package QrCode.Net
