greater commit than expected. informations from tank now stored into database; introduced a new switch "--recreate-database"

reactivated fallback and callback from lqs, fixed multiple lineins on engine level, having the problem that fallback does not start

checking free diskspace. send warnings (email & logging) and stop recorder if a critical value is reached.

found stupid bug in fetching programme from pv. added more or less random playlists. almost reactivated whole chain from fetching to liquidsoap

got too many data from pv. data is now filtered => easier debugging. now it is only possible to comment this to disable this function

enabled API call for liquidsoap state (enabled & connected streams, enabled & recording recorder, enabled lineins and enabled lineouts)

5 different recorders possible. 'last' missing thing on liquidsoap side: smooth transition between mixer.selects
