Revise default states and state changes in remote API

[reckart]

The default state when data is uploaded through the remote API presently does not make sense in all cases. Also, the annotation state and source document state are connected with each other and when changing the state of annotations, adding new annotations, or deleting annotations, then the source document state needs to be updated as well.

Annotation State	Curation State	Document State
all NEW	NEW	NEW
any IN-PROGRESS	NEW	ANNOTATION-IN-PROGRESS
all COMPLETE	NEW	ANNOTATION-COMPLETE
any	IN-PROGRESS	CURATION-IN-PROGRESS
any	COMPLETE	CURATION-COMPLETE

The document state must be updated whenever an action happens that could potentially affect it:

• change of annotation state through the UI or remote API
• upload of annotation through remote API
• deletion of annotation through remote API
• change of curation state through the UI or remote API
• upload of curation through remote API
• deletion of curation through remote API
