Update to nautilus-4.0

[redscorpse]

Please, add compatibility with nautilus 4.0. Even after modifying its version from 3.0 -> 4.0 the installation process exits with errors. I've tried to install it in a docker container and I get the following output after trying to run it:

root@e740e59d6a28:~/nautilus-pdf-tools# export LANG=C

^C

Also outside from docker I obtain the same errors.
