enhance logging

- bin/secop-server options -v and -q applied to console logger only
- level for logfile taken from general config
- option for automatic deletion of old logfiles
- added 'comlog' level (between debug and info)

This allows to run the servers by default with 'comlog' level on
the logfiles, which helps a lot for analyzing very rare communication
errors in retrospect.

to avoid spamming of the normal log files, comlog data is stored
separately, one file per communicator

+ redesign of remote logging (no more need of LoggerAdapter)
