Proof-of-concept implementation for setting docProperties in templates.
Create helper class to create documents from templates.
Add tests for doc property adapters.
Add tests for creating templates from word-files.

DocProps: Make IDocProperties adapt the newly created document

instead of the containing dossier, and set doc properties *after*
creating the new document, so the document can provide metadata
about itself.
DocProperties: Also provide ReferenceNumber and SequenceNumber for document.
