Change formation of Uppsala tickets

This fixes #6 but still only generates full price tickets, which is hopefully not too bad.
Thanks to evilperro for providing links to tickets with correct layout.

Here is a link to an APK with these changes: https://anonfiles.com/file/353eee7334dd4ce0c18a0cd9a1c769fc

Let me know if the link doesn't work or if I screwed something up.
