Fix #18 Make releative paths work using phars

[ptomulik]

This makes my test.tar.gz to work, so I believe it fixes #18. To test it, please tar -xzf test.tar.gz && cd test/ && doctum.phar update --force -v docs/doctum-relative.conf.php (using doctum.phar generated from this PR).

By the way do you have a GPG key ?

Not ATM. I mean I used GPG key(s) for email but it got me a lot of headache one day my signature expired, so I just abandoned my GPGs for a moment :)

If you still have the private key you can extend the expiration date and use them ;)
This can be useful to upload the key: https://gist.github.com/williamdes/0d49288fecf83bf491cc1e6366ae7c30#upload-the-key
I can help you if you want, let 2021 be a year with a working key to sign commits and tags ;p
