The Annotation import should only request ANNOTATE permission instead of WRITE permission

[Nicklas Nordborg]

I noticed (in #2302) that the Annotation importer request WRITE permission on file items. It should be enough with ANNOTATE permission.

Fixes #2303: The Annotation importer should only request ANNOTATE permission instead of WRITE permission

Actually, there is no ANNOTATE permission, but the RESTRICTED_WRITE permission is used for this. Needed a look at #2034 to refresh my mind.

The Annotation importer now requests the RESTRICTED_WRITE permission. The Item.File also needed to be updated so that the GUI enables this option (the permisssion is called Annotated in the GUI).

The Annotation batcher implementation also needed an upate since it checked for WRITE permission (as noted in #2033 but never corrected).
