Connectordb

- Fixed python 3 errors - should now work without issues on py3
- Tests are now run using a binary dist of ConnectorDB alpha
- Structured create support (a change in the core ConnectorDB api)

This alpha has compatibility with ConnectorDB's new permissions structuring. Several other smaller changes are also included.
- Logger no longer needs internet connection to start
- login by password switches to api key after auth (bcrypt is slow)
- changing API key of logged in device now also changes current auth
- Little bugfixes
- Python 3 compat

To be used for testing of ConnectorDB 0.3
