e642dcde added a helper fixed selection for the item type field.

However, it was not working when the schema was fetched from a remote URL.

This was reported to json-editor: https://github.com/json-editor/json-editor/issues/1165

This commit is a workaround which does not use $ref, hence duplicating some code.

This reverts commit e642dcde.

* Ignored transformation steps for Date and Published in fields because they are probably not necessary
* Also removed default value for Citoid selection

This reverts commit 0fe76147.

Not working with fetching remote schema for some reason

Moving some descriptions or description parts to infoText to simplify the json-editor form interface

Moving some descriptions or description parts to infoText to simplify the json-editor form interface

- Make the goals object an array of fields instead, to better compare with templates schema
- Improve documentation, for use with json-editor
