Heads up: F30 nautilus-python requires Python 3 compatibility

Hi all,

If you are maintaining a nautilus extension package written in Python,
please check that it supports Python 3 in rawhide/F30 (and fix it up if
it doesn't). Up until F29, nautilus-python used Python 2, but in rawhide
it's now switched to use Python 3.
