Channel scanner includes logging to cerr

[Nick Morrott <knowledgejunkie (at) gmail (dot) com>]

The following scanner methods include logging calls to cerr. Might it be useful to have them (or at least the first method whose cerr logging does not appear to be serious) log to a log target instead (perhaps VB_CHANSCAN)?

bool ChannelScanSM::TestNextProgramEncryption(void)


void ChannelScannerCLI::HandleEvent(const ScannerEvent *scanEvent)
void ChannelScannerCLI::InformUser(const QString &error)

For CLI - As far as I know, cerr is intended - It's a command line interface to the channel scanner, so is expected to output to cerr.

(In [20794]) Fixes #6688. Remove errant cerr debugging in channel scan signal monitor encryption testing code.. Note: The cerr output in the command line scanner are intentional so I've left those in place.
