add Ruby port
Support for "Thumbs Up" playlist

The get_thumbs_up_tacks() call returns a list of tracks that have
thumbs up (like) being set. This endpoint is also used be mobile
clients to show the automatic playlist "Thumbs up"/"Mag ich".
added nodejs port
Changed get_thumbs_up_tracks() to get_thumbs_up_songs()

This is for consistency with get_all_songs(). In addition, the term
song better represents the entirety of the data (audio + meta).
Added support to fetch information on children genres

To do this the dynamic parameter parent-genre can be used.
Updated the genre schema for child genres
Added a basic test for getting child genres
Added a test for get_thumbs_up_songs() which currently fails
