Implement GDPR-compliance

[terrymun]

Todo:

• Implicit consent is no longer valid. Explicit consent is required, which means that the consent message needs to be updated
• Enable IP anonymization for Google Analytics tracking. Refer to official docs for more info.
• Create/update existing privacy clauses
• Ensure that users can always delete personally identifiable data from Lotus Base database. They should be able to dissociate themselves from LORE1 orders, and remove user accounts entirely
• Ensure that upon account deletion, user is also unsubscribed from MailChimp mailing list
