Bug fixes

The release is not in a stable state and only for testing purpose.

Caution: The database schema may change without hook_update_N being implemented. Usage and API may not be documented. Installing a new unstable release entails uninstalling the project, thereby losing all data. Only for those who want an early preview of the project. Not yet suitable for shared development.

Getting this on a better monthly release cadence, enough issues fixed to warrant a new alpha release.
