Tor Lillqvist 4b7ecde829 When opening an attachment from the Mail app make sure it is opened read-only
Luckily the UISceneOpenURLOptions has a property openInPlace that
seems to be good to use for this. If openInPlace is false, that means
we should open the document read-only.

This is a stopgap fix to avoid the situation where the user does
changes to a document that is an attachment in an email message. Those
changes won't be saved anywhere they could be found later. Better to
keep the document read-only.

The ideal solution would be to ask the user right away where they want
an editable copy of the document to be stored. Later.
