IHG 1.7.0 Release Candidate 3

On IHG update, the default 'hostf.xml' is now empty and comes with lastModifiedTime stamp set to zero.
This initiates an update from the online server if 'host file automatic update' is set 'true'.

Jörn Reppenhagen and Ricardo A. Rivas are credited for their translation contribution.
