Blueprint to create Core Pages in existing Space

Some users who want to use projectdoc, may not have the privilege to create new spaces. If a space is created for them by an administrator, it is quite cumbersome to create the required pages by hand.

Therefore we add a page blueprint to create the space partition with those pages that would be created by the space blueprint.

Note that at this stage of development we only support one homepage per doctype in a space. Therefore you cannot (yet) create multiple core spaces.

Also note that this version requires projectdoc 1.4.0 or greater.
