Let ptVault.setAgePublic accept ptVaultAgeInfoNode in addition to ptAgeInfoStruct

In this case it now also works for non-owners of the age. Previously it only worked for owners because the ageInfoStruct does not contain the vault node ID, so it needed to be looked up somewhere, and that was in the AgesIOwnFolder.

Prerequisite for hood auto-bump (moul-scripts PR forthcoming).
Ugh. I forgot that this file is full of that eap-tastic stuff. Let's not worry about it for now then.
