Add Organizational event logging feature

This PR adds event/audit logging support for organizations.
By default this feature is disabled, since it does log a lot and adds
extra database transactions.

All events are touched except a few, since we do not support those
features (yet), like SSO for example.

This feature is tested with multiple clients and all database types.

Fixes #229
