a volume change should unmute

[lugdunum-1964]

Normally on audio devices turning the volume up or down will switch mute off. Moode doesn't handle it this way. Currently, when one has used vol.sh -mute a consequent vol.sh -up/-dn will have no effect until another vol.sh -mute is sent.

adding:

VOLMUTE=0
sqlite3 $SQLDB "UPDATE cfg_system SET value='0' WHERE param='volmute'"

after line 115 should change this to a more intuitive behaviour.
