new API responses
new GeoJSON responses
Bumped up lib versions
Merged dev branch:
- added support to display detailed icons of the vehicles - IC, SBahns, ICN - full units (locomotives and coaches) - @see the service_type value in the vehicles API response
    - (needed above) position helpers return now also the heading
- refactor the simulation timer, refresh more often for a more realistical movement of the vehicles
- start to use new FT ids
- use GMaps visualRefresh
