Rename Cache Templates from Contact Name to Contact ID
It is observed that smarty cache files are created for each contact with the name of the contact as the cached file's name. In our view it would be better from a Data Protection perspective for these to be contact ID numbers. This supports the "right to erasure" enforceable under GDPR - as users will not be likely to know that these cached files contain the contact's name it's possible that these could remain for some time.
