PCHK ignore existing configuratio

[splatch]

No worries, I am pumping up this topic as non-german user. Looking forward for new version of pchk.

To give you some details:
- Linux 4.4.0-1-rpi (raspbian/openhabian)
- Raspberry Pi model B plus 1.2
- LCN PCHK v 3.0 (lcnpchk300new.tar.gz), installed via script
- Service running on pi user
- Fixed startup script so it works (default one had some minor troubles)

Configuration file is owned by pi, as well as whole directories:
- /var/lib/lcnpchk
- /var/log/lcnpchk
- /usr/share/lcnpchk

Pi user is part of dialout group so it have access to serial ports.

From log entries I can't find any trace why it would fail. These log entries are shown each time.

<LogEntry timeStamp="2017-08-01T23:33:42" component="lcnpchk" code="0" isFatal="false">Started: /usr/bin/lcnpchk</LogEntry>

<LogEntry timeStamp="2017-08-01T23:33:42" component="lcnpchk" code="0" isFatal="false">LogDir is: /var/log/lcnpchk/</LogEntry>

I may suggest to add more debug information for accessing resources and printing out these to log in order to make debugging easier.

Kind regards,
