Subject: [PATCH] No use of CAM-Module and decrypting at EIT-Scan or not encrypted channels

SignalMonitor or Recorder initializes CAM-Module and sends CA_PMT for all
channels and programs, not only encrypted. They also do so for grabbing
EIT-Data with EIT-Scans. So all the time every few minutes during EIT-Scan
if channels change CAM is stopped and restarted (shows also up in syslog).
This fixes the behaviour. The CAM is only initialized and CA_PMT is sent if
a stream or program is encrypted and we want to record or look live-TV.
