Introducing Project creation

Authorised users can now create projects. The before and after insert
projects hooks take care of stripping unwanted urls and attaching
default node_type and permissions, as well as initialising a storage
bucket per project. We are temporarily switching to the development
version of the gcloud library, since it allows the creation of EU-based
buckets.
