Define Adapt structure via friendly ID

[chris-steele]

Feature description

The relationships between Adapt models (components, blocks etc) is described using MongoDB's ObjectIDs (via _parentId). At the moment this requires that the parent exists before the child can be inserted.

If we instead used _friendlyId to describe these relationships then inserts could be done concurrently. This would speed up import and content copy (clone) by reducing DB calls and HTTP requests (if DB is accessed over a network). It would also make casual analysis of DB tables easier during development.

N.B. would require #40

Can you work on this feature?
