refactor: improve arrange script (#170)

Re-writes the arranger script to polish off some inconsistencies with
the QBs:

- Removes all redundant values from the QB. All redundant values are
inferred at
"compile" time. Example, "questionBank" field from questions. 
- Removes all boilerplate files. If a given LO has no `annexes`, there
won't be
an `annex.json` and empty `annex` folder. These will be created if
needed.
- Add subjects as an LO. A subject now points to an LO as entry point.
