Once a channel is considered to be encrypted keep it flagged encrypted

Further research is required. Removing the fake CA 0000 seems not to work
as randomly here the flag disappears. So what was made from the beginning
seems for now the best compromis
Move Wake On LAN config to NetworkSetup

I suggest this is a better place for this config
Do not assume scrambled when service is not found in PAT
Change the screensaver to a 10th year anniversary screensaver
Make it easier for configs when boxes do uses slightly different procs

By introducing fileCheck that returns the name of the specific file if it
exists, so the SystemInfo does niet include True and False but instead of
True the filename of the specific (proc).
Standby: Avoid GSOD when tunerMask is not initialized

This could happen when you watching a recording and the box goes to
standby and then after a timeout to deepstandby. This might still shut
down the box in the situation another box is streaming. I have to find a
better solution to check the tunerusage later but for now I at least avoid
this GSOD
Find a more easy way to detect if a tuner is in use
