upgrade/migrate for Plone 5 if needed: isaw.policy 1.0.dev0

[paregorios]

This currently active addon provides three Dexterity types: location, publication, and library collection. We need it to work properly under Plone 5.1.

isaw.policy.location

The only objects of this type currently in the database are test items in my personal folder, and they are all currently throwing the error:

AttributeError('image',) (Also, the following error occurred while attempting to render the standard error message, please see the event log for full details: image)

I will create a separate ticket for addressing this error.

isaw.policy.publication

This content type is currently used widely across the site and is working fine.

isaw.policy.libcollection

This content type is not currently used anywhere on the site.
