A little less sucking

AKA. "Or finally I fixed support for IE"

Yeah, that's right. You are now able to generate PDFs / spell cards while using IE / Edge. My access to a windows-based computer is restricted so there haven't been much testing. I tried it in IE11 and Edge and it worked So I hope I can leave it there!

Let me know if it doesn't work for you.

But it would be nice if you include a Windows-version and IE / Edge -version for debugging.
