Initial Pod Content for Tests

[kjetilk]

We need to initialize the pod server under test, it needs a minimum of content. Since a root ACL is a minimum for a Solid Pod, at the very least this has to contain a root ACL.

We should then consider what can ease testing, and what shouldn't be there because it has to be written as part of the test. I think the opinions on this will change as the test suite is developed.

To this end, I propose we have a tar archive that can be downloaded an unpacked with the intitial contents.

The root ACL I have used for current tests is in https://github.com/solid/test-suite/blob/try/add-acl-check/testers/rdf-fixtures/start-acl.ttl

I think we can keep some of the structure that is currently installed by NSS by default, like the public, private and profile containers. I think we should also keep index.html and its acl.
