User Profile

User profile extended. 
I have some JS code to add an image preview in a div block. We can also create a custom form instead of using the default generated DJango form, adding the picture in other way. Nevertheless, I'm not sure how it will work once the picture is stored in Azure. I guess that it will be possible to recover the information in the same way we store it, and store a local copy if it cannot be linked directly from Azure.
