What's in the PR

• Centralize permission check for exporting documents into DocumentAccess class
• Permission check for exporting should consider the session owner, not the document owner

• Enable the "Disable export in annotation views" options in the "Details" tab of the project settings

• Visit the annotation page as the user that created the project (which should be a user with the "manager" permission level) and check that the document navigation and export buttons are present
• Use the open document dialog to open the document but this time selecting the other user from the dropdown at the top before selecting the document and check that the document navigation and export buttons are present
