Redo update
Redo update

- Start again from last version in hackerspace-ntnu/master instead of some already-customized local RPI version
- Forgo the RPI name. It's got nothing to do with the update to Python3 anyways
- Add a try/except statement that will load the Python3 urllib if the Python2 library cannot be loaded (I.E if you're using Python3)
- Update print-statements to Python3-valid syntax

Everything should still be valid Python2, assuming it was so before I started. I can't test this, however, as I cba to set up a Linux machine atm, and don't have Python2 on any of my PC-s.
