More flexible certificate editor

Currently Howspace Certificates are very limited and they all look pretty similart to each others.

It would be great to have possibility to add any kind of background image for the certificate and then use drag and drop to position information (like names and other profile fields, issue date etc) to the canvas. Then we would also need to allow changing font size and color for these draggable elements.

We have implemented a more flexible certificate editor, you can learn more about it here: https://help.howspace.com/en/articles/272110-certificate
