Added the option to deserialize based on ID instead of path. Also added a unit test that will check automatic template deserialization, which needs to be implemented later.
Added a lock for resolving path by id, to ensure correct handling if tests happen to run in parallel
Refactored item deserialization for use with pipelines
Added auto-deserialization of item templates, where possible and desirable
