Initialize the different radiobot components :
- Configuration loader, which will parse the json conf file and check
attributes conformity

- Player manager, which is in charge of controlling VLC and Alsa
(starting and stoping network streams, applying volume modifications)
- Radio manager, which is the overall manager, in charge of radio
